I wish to know the necessity of inclusion of conio.h in c programming.what sort of a command is conio.h? what is its function in a c program? what if i don't include this command in my program? what type of files are stored in conio.h
What is conio.h in a c program?
First of all, conio.h is itself a file, called as 'header file'. The way you include it in your C program is called "preprocessor directive". This will just place all the function definitions in conio.h, in your program while compiling.
conio.h is used basically to clear screen (clrscr()), get characters (getch(), getche(), getchar()), print in colors (cprintf()) and text based graphics programming (like printing in colors, moving around the screen by specifying the position, etc).
Reply:"conio.h" means that 'consol input and output' and it contain ur consol input and ouput functions and perform the DOS base tasks
Reply:it is a header file used in old MS-DOS compilers.we should include this header file in our program when we use the functions like clrscr(),getch() and getche.
Reply:Its a header file.Console Input Output

How to make a C/C++ program pause?
ok so I'm trying to learn C and C++, and whenever I execute the program it runs in the blink of an eye and I don't have time to see what it says, I remember there being a pause command or something that I could put in there somewhere that would wait for me to press enter, can you tell me where to put it and exactly what it's called? thank you
How to make a C/C++ program pause?
get in the habit of using getch() because it will work on all platforms (windows, unix, linux).
system("pause"); is Microsoft only.
Reply:Just add a getch(); before the last } of main. You will be fine.
Reply:There are a variety of ways -- basically you just need something that will cause the process to block.
One of these will work:
-Try reading in some input
-Use the sleep() command
-Use getch()
Reply:if the operating system is windows you can use
system("pause");
this function was declared in system.h I gues you should include the file. and for any operating system you can use scanf.

You could try Dev-C++. It's what I use and I've never had any problems with it. It comes with MingW (A minimalist GCC port to Windows), so you don't have to deal with setting your own compiler up. There's also CodeBlocks, but I don't have any personal experience with that IDE.

I'm trying to do a simple C program and I need to figure out how to check if a user input is an integer?
I'm doing a simple program that calculates sales tax to a purchase and displays the tax amount and the total cost. I'm using C (NOT C++) and the user will input the sale price then I am to convert that into the total sale and what the tax would be. Now I need to check the input that the user gives the program to verify that it is either a floating point or an integer. I think i need a float if they can use decimals right? Any help would be beneficial. Thank You For Your Time And Patience!!!

You can get sscanf to do much of the work for you. See below for some code I wrote to illustrate:

long i;
double f;
char s[MAX_STR_LEN];
} data;
} input_t;
int main(int argc, char *argv[])
{
char *s = argv[1];
input_t in = { NONE, { 0 } };
if (argc != 2) {
printf("\nusage: %s %26lt;n%26gt;\n",argv[0]);
exit(EXIT_FAILURE);
}
if ((strchr(s,'.') != NULL) %26amp;%26amp; (sscanf(s,"%lf",%26amp;in.data.f) == 1)) {

How to write a program in C by turning a hexadecimal to a decimal?
im having a hard time with this right now. help
write a c program that utilizes strings and numeric conversions
1. Read strings using a function you write called getStr ().
2. Write a function named hextodecimal () that takes in (only) a string parameter representing a positive hexadecimal number and return its decimal equivalent (integer). This function returns -1 if the string provided connotes to a negative number and/or is comprised of invalid characters.
-note: you may not use any library functions in this function- you must write all code necessary to enact the coversion and return the appropriate result.
-this function must accept both upper and lower case versions of the hex character.
-You may want to write an additional function that vets any string for invalid hex character
3. If original string is invalid, output an unambiguous message to the user and prompt for another input.
4. Output the original String, followed by its decimal equivalent. Clearly label which is which
How to write a program in C by turning a hexadecimal to a decimal?
I don't want to give you the entire solution, but I will give you some pieces to help, and comments where you need to fill in the code. This assignment justifiably restricts you from using library functions, which you would normally use to do much of the work for you. Use of fgets to get the user input is, I assume, allowed.
Note that I put the validity check in getStr, but part 2 of the problem statement wants you to check validity in hextodecimal, which is probably a better place to put it.

As someone who teaches programming, I can tell you that this approach to homework is only going to hurt yourself (and probably cause you to fail the course).
All the concepts you're covering in class build upon one another... so if you don't learn to do this week's homework, you won't be able to do any of the following weeks' homework (not to mention tests and larger-scale projects).
Reply:I am really sorry to say. But try it on your own, if it is a project given to you. The hint is "Use for loop".

I think you wrote a program as C++, but saved the file as a C file. For example, instead of naming the file MyProg.cpp, you called it MyProg.c. The compiler uses the file extension to determine if the program is a C program or a C++ program.
Reply:it is the error of your header files......either your library is corrupter or you need to set ur path by going in DOS shell.........
Reply:I wish you had provided your code because this looks like a relatively simple problem but wihtout your code it can be many types of things but one thing is for certain, thre previous responder (above this comment) is wrong in saying the file could be corrupt (that is just silly).....
Could you paste your code so i can take a look? Also it might be possible that your dev environment is set up to think its C specific or C++ (depending on which type you are trying to compile in)..
you should have either (or both):
#include %26lt;conio%26gt;

Notice you dont need to mention the ".h" extension for the conio portion if you are working with C++ code....And notice i didn't give the path to the library...the system knows where theya re already.

Help with c program?
can u please tell me how to write a c program to generate adam numbers from 10 to 100.
an adam number is one which satisfies the following: the reverse of the square of a number is the square of the reverse of the number. that is if the number is 12 then 12^2=144,the reverse 441 which is 21^2
Help with c program?
#include%26lt;stdio.h%26gt;
void main()
{
int num, rev, sq, rev_sq;
int rev_int(int);//Function to get reverse of any number passed as parameter
for (num=10;num%26lt;100;num++)
{
sq = num*num; // square of all numbers from 10 to 100;
rev = rev_int(num); // gets reverse of num
rev_sq = rev_int(sq);// gets reverse of square
/* we check if the reverse of the square of the number is equal to the square of the reverse of the number.If found true then print the number else go to the next iteration*/
if(rev_sq == rev*rev)
printf("\n%d is Adams number",i);
}//end of for loop
}
int rev_number(int num)
{
int rev = 0;
while(num%10 !=0)
{
rev = rev + (num % 10) * 10;
num = num/10;
}
return rev;// returns the reverse
}//end of function
This program could be done with lot less variables.
Reply:I would loop through each number. In the loop:
1. convert number to string. Hold on to string and its reverse.
2. Square the number
3. convert the square to a string and reverse it.
4. Convert string to a number and get square root
5. Convert square root to string and compare to reverse of string in 1.
If they are equal, you have an adam number. Print it and move on to next number
If they are not, then move on to next number
Reply:Sounds to me like what you need to write, first, is a function which takes an int number, converts it to a string, reverses the string, then converts the reversed string into an integer for returning.
Then, you write a loop, from 10 to 100, in which the current index is passed to your function. That gives you the two values that have to prove to be an adam. Then you square both of those numbers. Then you need to compare the two squares to see if one is the reverse of the other. For that, you COULD use your function again on one of the two squares, then compare what is returned with what was generated.
Which class is this for - number theory? discrete math? Just curious. This kind of thing is so fun..
Too bad it has to be in C - in Perl or Tcl the code would be a lot simpler...

Help in c++ program?
i want to write a program that calculates arithmatic and geometric mean in c++ , so i need help
Help in c++ program?
You aren't very specific with your request. How will the numbers be input (e.g. entered at the console, constant array, from a file) into the program? Any particular number format (e.g. integers, scientfic notation, simple floating point, double precision, fractions, sequence range, symbolic)?
Do you have a start to your program that you could share? This would help answer some the questions above. Is this a homework problem? Do you simply need hints regarding the general concepts for a computing solution or specific help on how to code certain aspects?
The arithmetic mean is pretty straight forward; it's just the average of your input numbers. However, the geometric mean can be done in several ways. I recommend taking the log of each input number, adding each log (i.e. multiply), dividing (i.e. nth-root) by the number of items, and finally the anti-log. Below is a quick attempt:
#include %26lt;math.h%26gt;
#include %26lt;iostream%26gt;
using namespace std;
int main () {
double nums[] ={8.3, 7.5, 1.9, 6.2, 2.4}; // input numbers
int numCount = sizeof(nums); // number of elements
double arithmetic_mean=0.0, geometric_mean=0.0;
for (int counter=0; counter%26lt;numCount; counter++) {
arithmetic_mean += nums[counter];
geometric_mean += log(nums[counter]);
}
arithmetic_mean /= numCount; // calc average
geometric_mean = exp(geometric_mean/numCount); // calc e ^ nth-root
cout %26lt;%26lt; "arithmetic mean = " %26lt;%26lt; arithmetic_mean %26lt;%26lt; endl;
cout %26lt;%26lt; "geometric mean = " %26lt;%26lt; geometric_mean %26lt;%26lt; endl;

Obviously, you'll want to substitute the appropriate input code for the nums[] array. Also, I assumed double precision calculations but you may have different requirements.
Help in c++ program?
You aren't very specific with your request. How will the numbers be input (e.g. entered at the console, constant array, from a file) into the program? Any particular number format (e.g. integers, scientfic notation, simple floating point, double precision, fractions, sequence range, symbolic)?
Do you have a start to your program that you could share? This would help answer some the questions above. Is this a homework problem? Do you simply need hints regarding the general concepts for a computing solution or specific help on how to code certain aspects?
The arithmetic mean is pretty straight forward; it's just the average of your input numbers. However, the geometric mean can be done in several ways. I recommend taking the log of each input number, adding each log (i.e. multiply), dividing (i.e. nth-root) by the number of items, and finally the anti-log. Below is a quick attempt:
#include %26lt;math.h%26gt;
#include %26lt;iostream%26gt;
using namespace std;
int main () {
double nums[] ={8.3, 7.5, 1.9, 6.2, 2.4}; // input numbers
int numCount = sizeof(nums); // number of elements
double arithmetic_mean=0.0, geometric_mean=0.0;
for (int counter=0; counter%26lt;numCount; counter++) {
arithmetic_mean += nums[counter];
geometric_mean += log(nums[counter]);
}
arithmetic_mean /= numCount; // calc average
geometric_mean = exp(geometric_mean/numCount); // calc e ^ nth-root
cout %26lt;%26lt; "arithmetic mean = " %26lt;%26lt; arithmetic_mean %26lt;%26lt; endl;
cout %26lt;%26lt; "geometric mean = " %26lt;%26lt; geometric_mean %26lt;%26lt; endl;
return 0;
}

Write a C Program to arrange a set of N numbers in an increasing order?
This is a standard sort program. You can use bubble sort which is the simplest and inefficient in case of a lot of numbers. You could use insertion sortor merge sort and quick sort. Quick sort is a good choice for large set of numbers. Any algorithms book will tell you how these sorts work. You should refer those and try and code. If you are a beginner then I suggest u learn bubble sort. Its easy to learn and understand.
Reply:The C API has a built in implementation for sorting using quick sort, which is very efficient. The man, page with details on how it works is at:

Write a C program in a Unix Operating System to count number of word in a file.?
Write a C program in a Unix Operating System to count number of word in a file. The main process will read from the user the file name and a positive number N which represents the number of lines in this file. Accordingly, the main process will greate N processes. E#ach process i will count and print the numbe of words in i-th line of the input file, where 1%26lt;= i %26gt;=n. The children processes should be implemented using the system call exec. Finally, the main rocess should print out the total number of words in the input file.
Write a C program in a Unix Operating System to count number of word in a file.?
That sounds like a homework problem to me.. albeit an interesting one. While you are at it, remember that given a sufficiently large value of N, you could hose the box with too many execs.
I will abstain from trying to code it since I am a bit short of time. but briefly, I would approach this problem thus
- A method that takes a line and counts the number of words in it
- There should be a global counter for words in the file.
- the method mentioned above should enter a synchronous block to update this global counter
- The main program should invoke N such threads and to each thread, pass the ith line in the file.
- Each of the threads should invoke the method mentioned above.
- Once each thread returns, the main method should output the global count
My 2 cents!

Write a C Program to declare an array for 2 0 floats.?
Write a C Program to declare an array for 2 0 floats. Accept the values from the user sort the two arrays in descending order. Merge the two arrays into a new array and display the new array.
Write a C Program to declare an array for 2 0 floats.?
what did you mean by 2 0 floats? is it 20 floats or 2.0 floats or what?
if you said 2D floats or 2 array of floats, i understand.
Let say you need to declare a 2D floats, so it will become like this:
float twod_flArray[20][20];
or
float twod_flArray[2][2] = {{1.0,2.0},{2.0,3.3}};
Sorting problem may be done by using a bubblesort algorithm.
There are a lot of it in the net, try to search.
To merge it, just append into the new array.

I'm guessing you would get a better response if you asked for help -vs- what appears to be a command to write it for you

Sounds like a fun homework assignment for YOU TO DO YOURSELF.
Reply:I'd use a spreadsheet instead of C++. I'd copy the text file into the spreadsheet. Then the data can be sorted easily just go to data and sort. If this is for a class your book will tell you the correct commands to input, sort the data and then output the data into a text file. I have never used C++ but in basic an array was a place to store data. I would think you could use input or a similar command to input the data from the file then use display or a similar command to show the file on screen. Then use sort or a similar command to sort ascending or descending. Then use display or a similar command. Then use write, output or a similar command to make the output file.
Reply:read a tutorial and do it yourself, it's really easy.

for(i=0;i%26lt;n;i++)
scanf("%d",%26amp;a[i]);
big=a[0];
printf("the biggest no is",biggest(a,n,big));
getch

Can anyone convert the below c program to c++ program or just tell how to find the biggest no among the n no?
Save as your file with extension CPP and replace header file stdio.h with iostream.h and also add conio.h for clrscr() and getch().
now replace all scanf() with cin%26gt;%26gt;num and you have no need to specify format characters(%d or %c) and also printf () with cout%26lt;%26lt; num without any format specfiers..
Reply:replace stdio by iostream in header
replace scanf("%d",%26amp;n) by cin%26gt;%26gt;n and so on
replace printf("...................",d,g,h) by cout%26lt;%26lt;".........."%26lt;%26lt;d%26lt;%26lt;g%26lt;%26lt;h; and so on
it will work
Reply:that also works in C++ no need to convert except for the libraries i think getch() is in stdlib.h and also use cin and cout instead of printf and scanf in the ipstream.h

Can a unconditional loop of C program harm my processor???
Can never end(continious) program of C program harm my processor or any part of my PC or LAPTOP?????
Can a unconditional loop of C program harm my processor???
If you let it run long enough yes it could, but if you stop it fairly soon, such as shorter than 10-20 minutes it shouldn't do any harm to the system.
Reply:Not if the computer has been properly designed to be able to cool the cpu under worst case conditions.
You may want to have your program sleep for a few microseconds between loops to reduce the percentage of cpu usage.
Reply:No, not normally, although if it included two disk functions that slammed the drive head back and forth (instead of repeatedly addressing a buffer) it would wear on the machine eventually. Otherwise you are just slamming electrons back and forth and running down the battery.

What Program/Tool Can I use TO Host A Java/C Programming Competition? I want online problem submission?
I have ot find a program to be the server for a competition, i need some help in what to use. I want the server at minimun to accept java and c/c++ source files from teh user, as well as a correct/incorrect message.
Any Help is greatly appreciated!!!
What Program/Tool Can I use TO Host A Java/C Programming Competition? I want online problem submission?
As long as I have been programming, I have never heard of a SERVER that can CORRECTLY identify which programs are right or not, seeing as you could have many different styles of programming and have the same output.
If you want something like this, you can either make it yourself or you can pay someone to make it for you (a good idea would be a person who writes in php or some other advanced scripting language). This would be A LOT easier to do if it was a local (LAN based) contest. The internet complicates the whole process.
Good Luck.

i type c++ program my seeing my text book and i used to save it, when i go to the folder it is in the form of text how do i convert it into program
I am new to c,c++ program?
You need some compiler to convert your text to program (exe). Boreland, or Microsoft VC++ or if u use linux u can use gcc.
Linux
------
1.Type pgm and save as a.c
2. from shell $gcc a.c
3. this will compile %26amp; create a.out
4. ./a.out will show u the result.
Windows
---------
Use any IDE that is best.
Refer "Balagurusamy" books he added topic how to compile the pgm in multiple IDE as an appendix
Reply:You have to compile it using a C++ compiler.

Help with this C++ Program?
The snack bar sells only six different items : a sandwich, chips, pickle, brownie, regular drink, and a large drink. All items are subject to sales tax. Set prices for the pdocuts.
The program should repeatedly display the menu below until the sale is totaled. The program should keep a running total of the amount of the sale based on the costs that you place in constants for each of the food items. The running total should be displayed somewhere each the menu is displayed again.
S - Sandwich
C - Chips
P - Pickle
B - Brownie
R - Regular Drink
L - Large Drink
X - Cancel and start over
T - Total the sale
If the sale is canceled, clear your running total and display the menu again. When the sale is totaled, calculatae the sales tax based on 7%. Print the final total due on the screen.
You can use your own functions to design a solution to the problem. You are required to use a function to calculate the sales tax. Other use of functions is up to you.
Help with this C++ Program?
i think that someone need to do their own home works ;)
Reply:I agree that you should do your homework, but since it looks like you have put forth some effort, I have no problem helping.
First off, declare your values for sandwich, chips etc in the beginning. There is no reason to keep re-assigning them.
double sandwich = 4.00;
After you have done that, change the part that prints out the menu to use those values instead of hard coded ones:
cout %26lt;%26lt; "S - Sandwich: $" %26lt;%26lt; sandwich %26lt;%26lt; endl;
Your sales tax function should be something like:
double getSalesTax(double amount)
{
return amount * .07;
}
you should probably have a printTotal too
void printTotal()
{
cout %26lt;%26lt; "Subtotal: $" %26lt;%26lt; setprecision(2) %26lt;%26lt; running_total %26lt;%26lt; endl;
cout %26lt;%26lt; "Sales Tax: $" %26lt;%26lt; setprecision(2) %26lt;%26lt; getSalesTx(runningTotal) %26lt;%26lt; endl;
count %26lt;%26lt; "Total: $" %26lt;%26lt; setprecision(2) %26lt;%26lt; (running_total + getSalesTax()) %26lt;%26lt; endl;

setprecision is in iomanip I believe.

You haven’t mentioned your OS. So I’ll assume it’s Linux. The big players are GTK+ and QT. QT is the choice for KDE apps and GTK+ for Gnome. WxWidgets is popular as a cross platform toolkit, especially on Windows. Take a look. Each toolkit will have samples with source code.

i am a C novice, and my teahcer wanted to make a program using for to sum the numbers that where before a certain number
for exmple input 5
5+4+3+2+1=15
#include%26lt;dos.h%26gt;
#include%26lt;conio.h%26gt;
#include%26lt;stdio.h%26gt;
void main()
{
int total,number,contador;
clrscr();
printf("inserte numero\n\n\n");
scanf("%d",%26amp;numero);
for(contador=numero; contador%26gt;0;contador--)
{
clrscr();
resultado1=numero+contador;
resultado1=resultado1+resultado1;
}
printf("%d es el resultado\a\n", resultado1);
getch();
}
so, contaodor is supposed to decrease so that the 5,4,3,2,1 are added to 5, and the result should be 15
but, the program simply sums 5+1, the last number before 0, so the total is 6 and the other line insisde the for just does a stupid 6+6
i think the solution should be very easy but im tired as hell..
anyone can help please :P?
Help with a very simple C program using 'for' to sum numbers?
Hi Jose,
Try this out :
#include%26lt;dos.h%26gt;
#include%26lt;conio.h%26gt;
#include%26lt;stdio.h%26gt;
void main()
{
int resultado1=0,numero,contador;
clrscr();
printf("inserte numero\n\n\n");
scanf("%d",%26amp;numero);
for(contador=numero; contador%26gt;0; contador--)
{
resultado1 += contador;
}
printf("%d es el resultado\a\n", resultado1);
getch();
}
Reply:int result;
for(int i = contador; i %26gt; 0; i--)
{
result += i;
}
printf("%d", result);
Reply:Everyone is correct. You are just missing something in your code. Declare resultado1 up top and it should compile correctly as you intended it.

Pelase help me with this C program?
How can i do this program in C format the one that starts like this
#include%26lt;stdio.h%26gt;
main()
{
printf
scanf
}
This program will simulate a grocery store check out.
You will ask the user how many items they are purchasing today.
Then read in the individual prices one by one and add them together to get a total.
Tell the user the total of their purchases and ask them how much money they are giving you to pay for their purchase.
If they give you enough money, compute and display their change.
If they give you the exact amount display a message that they get no change.
If they do not give you enough money, tell them that and ask them to try again. Make sure they give you enough and don't compute their change until they do give you enough money.
Pelase help me with this C program?
Wow, that's a bit long.
First of all the app will ask the user for an integer input and store it in an int variable.
int count;
printf("How many groceries do you wish to buy?");
scanf("%d",%26amp;count);
Once you've done that, the app will need to use a for loop in order to sum the total cost. You need to declare first another variable (call it "sum"). Also declare a temporary variable to store the input given each time (call it "temp").
for(int i = 0 ; i %26lt; count ; i++)
{
printf("What's the next price?");
scanf("%d",%26amp;temp);
sum += temp;
}
Now print the total amount (I bet you can write it yourself). After that, you need to get the amount of cash given by the customer (let's store it in a variable called "pay"), and then write 3 if statements that deal with each and every one of the following options: Not enough money, the exact sum, and too much.
Not Enough: (Notice the use of a while loop)
while(pay %26lt; sum)
{
printf("You didn't give enough money! You need %d more",sum-pay);
scanf("%d", %26amp;temp); //Since we don't need temp anymore we can use it here
pay += temp;
}
Exact sum:
if(sum == pay)
printf("No change");
Too much:
if(sum %26gt; pay)
printf("Thank you. Your change is %d",pay-sum);
Reply:Your missing 2 main functions, actually 3, but that complicates things

What is wrong with this c++ program?
I just started programming in C++ and need help. I created a basic adding program and it won't compile. What is wrong with it?
Here's the program:
//This program will add numbers
#include %26lt;iostream%26gt;
#include %26lt;cstdlib%26gt;
#include %26lt;cstdio%26gt;
using namespace std;
int main (int argc, char *argv[]);
{
char quit;
quit = '\0';
while (quit != 'q')
{
int x;
cout %26lt;%26lt; "enter the 1st value";
cin %26gt;%26gt; x;
int y;
cout %26lt;%26lt; "enter the 2nd value";
cin %26gt;%26gt; y;
int a;
a = x + y;
cout %26lt;%26lt; "The sum of the two values is:";
cout %26lt;%26lt; a %26lt;%26lt; endl;
}
system("PAUSE");
return 0;
}
What is wrong with this c++ program?
For starters, you DONT want a ; after your main function :
int main (int argc, char *argv[]);
^ WRONG!
Update: And the new errors are?
You probably need different header files -- specific to the compiler you are using. Which compiler are you using?
Try using stdio instead of cstdio and stdlib instead of cstdlib
Reply:along with above advices use
while(getchar(quit)!='q')
and add these lines after cout%26lt;%26lt;a%26lt;%26lt;endl;
cout%26lt;%26lt;"Enter q to quit";
Reply:mdigitale is correct about the stray semicolon after main. He expressed it a bit inaccurately though.
You don't want a semicolon after a function *definition*. You want it after a declaration. In your case, you are defining main. You are writing the code inside it. Careful on the semicolons.
mdigitale is however, incorrect about the headers. %26lt;iostream%26gt;, %26lt;cstdio%26gt;, and %26lt;cstdlib%26gt; are the correct forms. The change was made in the 98/99 revision of C++. Yes, that's nearly a decade ago. If you try to compile with the C style header format in any modern compiler, you will get a diagnostic message. Usually as a warning.
Just as a note, cstdlib isn't needed because you use no functions from it.
After removing the semicolon, you should have no further errors. If you do, do tell us **verbatim** what those errors are. As magical programmers seem to be, we aren't psychics. We do not read your mind remotely.
Your logic has an error in it. The while loop depends on quit, but quit will never change because you never asks for user input.
When posting code, please use a pastebin like http://www.rafb.net/paste/ . You can google for other nopaste or pastebin sites.The idea is to preserve indentation, and perhaps have formatting so we can actually read your code. Then we can help you.

I'm having trouble running my C++ program after i compile and link it?
I just start programing in the C language. I Use Microsoft developer studio standard (if there something better, add that, though i can't choose you as best answer unless you answer my actual question). I'm also learning from "C for dummies".
well, enough of that, I made my first program. all it does is say "goodbye crule world" (in contradicts the "hello world" prgram.) So I compiled and linked my .C file into a .exe file. when i open the source file and go to "run GOODBYE.EXE" it works fine. but when i got to my documents and open the .EXE file there, it breifly opens and then closes. and i didn't push the any key (which my book says is enter :) )
so, help me out here, why doesn't it stay?
I'm having trouble running my C++ program after i compile and link it?
When you run a console program from the windows explorer, it opens a console, runs your program, and then the console closes as soon as your program finishes. Whereas, when you run it in visual studio, the compiler doesn't close the console window right away, and waits for your input first.
There are two ways to get around this.
One way is to run your program from the command line instead of the from the explorer. If you know how to use the dos command line, this is your easiest option.
The second way is to make your program pause before terminating. To do so, add the following line at the end of main():
cin.get();
Reply:The program runs. Here's the deal windows runs fast enough that it will open a cmd windows display "goodbuy crule world" read the return 0; in your code and exit all in about the time it takes to blink! ( I've had the same problem before ). Try adding this to the end of your code.
#include %26lt;iostream%26gt;
using namespace std;
cout %26lt;%26lt; "enter any number to exit /t" %26lt;%26lt; endl;
int completely_useless_num;
cin %26gt;%26gt; completely_useless_num;
return 0;
// happy coding
Reply:Ok, first you need to get your terminology right. This is computer programming and computer science: precision is important. C++ and C are different. I’m assuming you’re are writing a C program. Not a C++ program. Second, there’s no such thing as Developer Studio. I’m assuming you are using Visual Studio? You also should mention the version. It’s important. VS 2005? VS 2003? VC++ 6? Don’t skimp on details.
Next, don’t use C for dummies. Think about it for a moment. If you find C difficult, you need to pick a different programming language. C is naturally complex. It’s a low level language, so you don’t have much logical abstraction. And it has quirks. It is difficult. The book I recommend is K %26amp; R’s The C Programming Language. Only that. It is the de facto book on C, and you should get that. If you find C too difficult to start with, pick a different language, please.
Now, onto the actual program. The program you created is what is known as a console program. If you go to start-%26gt;run-%26gt;”cmd”, you get a console or command line. You should learn to run programs from there. As a beginner, it’s acceptable to use a kludge: #include %26lt;stdio.h%26gt; and at the end of the main, add getchar();
Reply:Windows automatically closes any console program launched from the file browser as soon as it is finished running. So once your program prints its message, there's no more code, it exits, and Windows closes it. This only takes a millisecond or so to process, much too fast for a human being to read.
Just add this line:
getchar();
Put it in your program right under your printf() statement. This will cause the program to wait for one character of input. It doesn't do anything with the input since the function isn't assigned to any variable. But it will wait, as long as it takes, to get at least one character from the user. Until it gets that, it won't exit.
Reply:lol You know that C++ and C are two different languages right? I could help you in C++ but C might have a different way of doing it.
before the last return statement put
cin.get();
cin.get();
It'll pause the screen, waiting for input from the user (clicking any button).
I put 2 down b/c 1 doesn't always work. This is the simplest way I've found to do it. And I'm sorry if that doesn't help in C, I know how frustrating programming can be.

Help me with a c++ program plz?
Hey, I'm supposed to write a c++ program that plays the game hangman.
It's supposed to read in a bunch of words from a file that contains strings, it has to store the strings in an array of strings. Then print out a series of underscores and letters which represent the answer like s__ francis__. The user has to enter a letter, if it's incorrect print out a part of a man on the gallows with dashes and such. If it is correct put it in the word. Also I'm supposed to use 2 functions in the program. The file that the words will be read from will be up to 1000 lines long. And the program has to use strings to store the words not arrays.
Can someone plz explain how to do it or help me get started plz
Im not good with strings or arrays, im not sure how exactly i'm supposed to read stuff in from the file and store it in an array of strings
Help me with a c++ program plz?
Dude! This is not going to be a quick simple little program.
Id break it into chunks as follows:
1) Write a routine to read in the words and store them into the array of strings. Here are a couple of variables:
string myWords[1000];
short wordCount=0;
This could be a function or could just be at the beginning of main().
2) Write a function to display the gallows. This is probably the hardest part. I would suggest making your display just a few arrays of data and then assigning values as needed. For example, your gallow initialization could look something like
char gallows[10]={
" //========= ",
" || ",
" || ",
" || ",
" || ",
" || ",
" || ",
" || ",
"/||\ ",
"

Reply:__________"}
Then, your routine would know that when one letter is wrong, it should change gallows[1], [2], and [3] to include characters for a head. When the second one is guessed wrong, 4, 5, and 6 get the body parts and so on.
The screen should be cleared each time you display the gallows. You should also display the letters under the gallows and guessed letters above it.
This means you'll need an array (size 26) for missed letters and another array, initialized with underscores and the size of the maximum word you expect.
You'll need to create another function to perform the letter check. This should make sure the letter hasn't already been used and if not, see if the letter exists in the word being guessed. If it doesn't, then the letter position corresponding to their guess is filled in within the missed letters array and the count (for the gallows display) is increased. If it is correct, replace the appropriate underscore with the correct letter.
There's an awful lot more to a program like this and it could take pages to provide more help. I'd suggest you work on small parts and then assemble those working parts to make the whole program.
Reply:You may want to make an object that contains a string and forward/backward pointers for a linked list. When you read a word, use new to get an instance of the object, put the word into the string member of the object and link the object to a list of other such objects. You can even sort the list if you need to. (It doesn't use arrays. Maybe that is what your instructor expects).
Be sure to delete all the objects in the list when you exit. It's good form.
Reply:The most eazy way is to use STL:
#include %26lt;string%26gt;
#include %26lt;vector%26gt;
using namespace std;
typedef vector %26lt;string%26gt; string_vector;
...
To add string to your array (i.e.vector):
void add_string( string_vector %26amp; sv, const string %26amp; s )
{
sv.push_back( s );
}
To get string from array:
string * get_string( string_vector %26amp; sv, int index )
{
size_t sz = sv.size();
if( !sz )
return 0;
if( index %26gt;= sz )
return 0;
return %26amp; sv[index];
}
...etc.

Reply:You may want to make an object that contains a string and forward/backward pointers for a linked list. When you read a word, use new to get an instance of the object, put the word into the string member of the object and link the object to a list of other such objects. You can even sort the list if you need to. (It doesn't use arrays. Maybe that is what your instructor expects).
Be sure to delete all the objects in the list when you exit. It's good form.
Reply:The most eazy way is to use STL:
#include %26lt;string%26gt;
#include %26lt;vector%26gt;
using namespace std;
typedef vector %26lt;string%26gt; string_vector;
...
To add string to your array (i.e.vector):
void add_string( string_vector %26amp; sv, const string %26amp; s )
{
sv.push_back( s );
}
To get string from array:
string * get_string( string_vector %26amp; sv, int index )
{
size_t sz = sv.size();
if( !sz )
return 0;
if( index %26gt;= sz )
return 0;
return %26amp; sv[index];
}
...etc.

How do you write a c program to calculate the roots of the 2nd order equation: ax^2+bx+c?
The program should include the solutions for the following special cases:
a. a=0
b. b=0
c. c=0
d. a, b, c %26lt; 0
e. b^2 - 4ac %26lt; 0
How do you write a c program to calculate the roots of the 2nd order equation: ax^2+bx+c?
See the wikipedia article below for information about quadratic (i.e. 2nd order) equations. It describes the quadratic formula. The most common way to write a computer program for this task is to write a C version of the quadratic equation.
Then test, test test! Test each of the special cases, as well as more "normal" cases.

Need help with a C++ program, I need to know how to make the program end when the statement is false?

You have more than one area in which the user enters a choice, If you are asking how do you end your program at a point in which the user has entered invalid information,
switch your
if (choice %26lt;=0 || choice %26gt;=5)
cout %26lt;%26lt; "You did not choose a correct number please try again." %26lt;%26lt; endl;
To:
if(choice %26lt;=0 || choice %26gt;= 5)
{
cout %26lt;%26lt; "You entered invalid information" %26lt;%26lt; endl;
return 0;
}
The bottom switch statement you would add:
default:
cout %26lt;%26lt; "You entered invaid number" %26lt;%26lt; endl;
return 0;
Anytime you return from main, the program is over.
Reply:first of all you need a default case in your switch down at the bottom, but what statement are you talking about?
