In C++ program how to use "enter" key to quit program?
This is a simple one. Here's the answer...





main()


{


char ch;


a:ch=getch();


if(ch=='\n')


exit();


else


goto a;


}





You may include the header file stdlib.h as exit function is defined in that file.
Reply:check the key entered


the ascii char representing the enter key is '\r'


then use the exit function
