My question is can you check for keyboard input within a loop without halting the loop itself.

while(condition)
{
    if(keyboard input)
        action;

    more code;
    more code;
    more code;
    more code;
}

edit:
I'm using a linux machine.

Hard to do without operating system-specific functions. Best that you edit your question to specify which OS you are targeting. – user4581301 Feb 21 '16 at 08:32

Thanks for that link, looks interesting, I didn't think to use ncurses. – Axios Feb 21 '16 at 08:40

The select statement approach in the second answer is also interesting. I've never tried that before. – user4581301 Feb 21 '16 at 08:41
