getch in c

getch in c language: getch function prompts the user to press a character and that character is not printed on screen, getch header file is conio.h.
C programming code for getch

/* getch in c example */
#include
#include

main()
{
printf(“Waiting for a character to be pressed from the keyboard to exit.n”);

getch();

}

When you will run this program, the program will exit only when you press a character, note that we are talking about a character so try pressing numlock, shift key etc (program will not exit if you press these keys) as these are not characters. Also try the above program by removing getch(), in this case program will exit without waiting for a character being pressed from keyboard.
