You could use get() or something similar.

Why not system("pause")?

Because this is system dependent and is not portable c code. But if you want run your program only in windows environment that's ok.

Kind regards.

This will hog the cpu while waiting for a keypress.
Try to sleep for 1 second between calls to _kbhit
