getche function prompts the user to press a character and that character is printed on screen.
#include<stdio.h> #include<conio.h> main() { printf("Waiting for a character to be pressed from the keyboard to exit."); getche(); return 0; }
Run this program and press a character. Then view the user screen (Alt+F5) if using turbo c. You will find the character printed on the screen if you pressed a printable character. Try pressing enter or tab key (non printable) characters also.
