int _kbhit( void );
The _kbhit function checks the console for a recent keystroke. If the function returns a nonzero value, a keystroke is waiting in the buffer. The program can then call _getch or _getche to get the keystroke.
The _kbhit function returns a nonzero value if a key has been pressed. Otherwise, it returns 0.
