// Description:   The example program shows how to read a computer
//                keyboard keypress in real-time in Windows.
//                When you press a key on the computer keyboard, a message
//                is printed which shows which key was pressed.

int main(void) {
   int ckey;           // storage for the current keyboard key being pressed

   printf("Press \"q\" to quit.\n");
   while (1) {         // event loop
      if (kbhit()) {   // If a key on the computer keyboard has been pressed 
         ckey = getch();
         printf("The computer key pressed was: %c\n", (char)ckey);

/* Windows I/O functions used in this program:
 *
 * int kbhit(void) -- Returns true if a key on the computer keyboard has
 *                    been pressed, or false if no key has been pressed.
 * int getch(void) -- Returns the key which has been pressed on the computer
 *                    keyboard.  Returns -1 if there was not key press.
