Hey, I'm learning to prgram in C++ with the help of a book I bought. However, for some reason all the exercises in the book do not have cin.get() or system("PAUSE") and do not mention anything about using these to stop the program from closing (very frustrating!)
Here is my program that has been copied straight from the book and is closing after I enter a number. ( Or after I press enter after I have entered the number in the case that I have put a cin.get() in)
#include %26lt;iostream%26gt;
using namespace std;
int main( void )
{
int number;
cout %26lt;%26lt; "Enter a number" %26lt;%26lt;endl;
cin%26gt;%26gt; number;
if (number %26gt;= 1 %26amp;%26amp; number %26lt;= 100 %26amp;%26amp; (number % 3 == 0))
{
number = number * 2;
}
else if (number %26gt;= 1 %26amp;%26amp; number %26lt;= 100
%26amp;%26amp; !(number % 3 == 0))
{
number = number * 3;
}
else if (!(number %26gt;= 1 %26amp;%26amp; number %26lt;= 100))
{
number = number * number % 3;
}
cin.get();
cin.get();
return 0;
}
Help would be great thanks.

Need help with C++. Program closing on a simplish program.?
IMO, the reason why the exercises don't have a system("pause") is because not all C++ editors/IDE need them. Dev C++ is the only IDE I know that closes after program execution.
In your program, I don't think that you need the cin.get(); lines, just 'system("pause")' before the 'return 0;'. You may also want to display your programs result, just add a 'cout %26lt;%26lt; number;'.
Reply:Hey thanks... the cout%26lt;%26lt;number was all I needed. I must have forgot that.
I'm using the beta version of Microsoft Visual Studio 2008. Report It

are you in ap college and is this question was given to you by sameer sir if yes then only i can help you he gave me that assignment two years back
Reply:i never got answers to such question and further more all such questions atleast mine get deleted so good luck in finding an answer to ur question even if u are just asking out of curiosity(not likely)(or because of lack of good teachers) its regarded as doing ur homework or uni assignment for you.

Write a C++ program to print a triangle composed of a symbol.?
Write a C++ program to print a triangle composed of a symbol. The number of lines and the symbol should be entered as input from the keyboard. For example, if the input values are * and 7, the output is as follows:
Do you wish to continue? (y = yes, n = no): y
Enter the symbol to be used to draw the triangle: *
How many lines do you want the triangle to be? 7
*

Thank you for using this program.
(The triangle really isnt a right triangle it should be a normal one but it doesnt show up right here.)

After a C++ program, is there any way to make it not say...?
After a C++ program, is there any way to make it not say press any key to continue...? I am using Dev-C++ 4.9.8.0.
HELP!!!!!!
After a C++ program, is there any way to make it not say...?
that is just the debugger running it. Run it normally through a normal DOS console or command prompt and you won't see it. Basically that is there to keep the window from closing without user interaction.

Problem on C program(strings)...please try to solve.?
write a C function void str_copy_drop(const char * string1, char * string2, char ch)
which copies the string string1 to string2 but with all occurrences of the character
passed as parameter ch omitted.
HERE IS WHAT I HAVE TRIED: its funny but can you check it and write me a correct program..
#include%26lt;stdio.h%26gt;
#include%26lt;string.h%26gt;
void str_copy_drop(const char *string1, char *string2, char ch);
void str_copy_drop(const char *string1, char *string2, char ch)
{
char *s1[20],*s2[20];
FILE *input;
input =fopen("string.txt","r");
fscanf(input,"%s",%26amp;s1);
s2= strcpy(s2,s1);
printf("\ncopied string is %s\n",s2);
}
above programs is wrong...i need solution for question described above..
Many thanks!!

Use this function instead of yours. It would work fine.
void copy(char *s1,char *s2,char ch)
{
while(*s1!='\0')
{
if(*s1!=ch)
{
*s2=*s1;
s2++;
}
s1++;
}
*s2='\0';
}
U can ask more such..

You'll have to format the indentation yourself, as yA doesn't allow tabs.
Reply:you would have to go through the string, character by character and compare it with the parameter ch. if it matches then dont copy it to the new string. you need to know the length of the string so you know how many characters to compare.
pseudocode:
set 2 counters to 0
get length of string
loop "length of string" times
if string1[couter1] = !ch
copy string1[counter1] to string2[counter2]
increment counter2
loop until at end of string1
just a note (going by your function declaration), the file should be opened outside of the routine and read. then pass the pointer to the string. you dont need the "char s1, s2 pointers since you are passing the string pointers to the function (which you are not using by the way).
