stop infinite loop or process with press a specific key in c

Question

I've just thought about the ctrl+c in the terminal which as you know stop every process, updating, an infinite loop and etc. then I start to program a code which prints the Fibonacci sequence in an infinite loop and trying to stop it with a specific key but I have no idea how it's possible.

Can anyone help me with this problem?

Thanks In advance

Hy man you can do something like this:

#include <stdio.h>
#include <conio.h>              // include the library header, not a standard library

int main(void)              
{
    int c = 0;             
    while(c != 'key that you want')             // until correct key is pressed
    {
        do {                
            //Fibonacci sequence
        } while(!kbhit());      // until a key press detected
        c = getch();            // fetch that key press
    }
    return 0;
}
