Function getch in C program prompts a user to press a character. It doesn't show up on the screen. Its declaration is in 'conio.h' header file. The function is not a part of standard C library.
C programming code for getch
#include <stdio.h>#include <conio.h>
int main()
{
printf('Waiting for a character to be pressed from the keyboard to exit.n');
{
printf('Waiting for a character to be pressed from the keyboard to exit.n');
getch();
return0;
}
return0;
}
When you run this program, it exits only when you press a character. Try pressing num lock, shift key, etc. (program will not exit if you press these keys) as these are not characters.
