Dec 16, 2019 The Microsoft-specific function name kbhit is a deprecated alias for the kbhit function. By default, it generates Compiler warning (level 3) C4996. The name is deprecated because it doesn't follow the Standard C rules for implementation-specific names. However, the function is still supported. Kbhit- it's use and alternatives, and input buffer lag. Hello fellow coders, I've been working within the console on the logic of plotting. Kbhit is present in conio.h and used to determine if a key has been pressed or not. To use kbhit function in your program you should include the header file “conio.h”. If a key has been pressed then it returns a non zero value otherwise returns zero. Oct 22, 2017 kbhit is present in conio.h and used to determine if a key has been pressed or not.

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.
Try running the program by removing getch. In this case, it will exit without waiting for a character hit from the keyboard.

Function getchar in C
#include <stdio.h>int main()
{
int c;
c =getchar();
putchar(c);
return0;
}
{
int c;
c =getchar();
putchar(c);
return0;
}
A common use of getch is you can view the output (if any) of a program without having to open the output window if you are using Turbo C compiler or if you are not running your program from the command prompt.
