"SLEEP" with no argument will sleep until a button is pressed on the keyboard (including modifier keys such as shift or control). Also, pressing a key while SLEEP is waiting for a specific amount of time (as above) will end the SLEEP.

The function <tt>sleep</tt> needs seconds, which are read from the standard input.

#include <unistd.h>
int main()
{
unsigned int seconds;
scanf("%u", &seconds);
printf("Sleeping...\n");
sleep(seconds);
printf("Awake!\n");
return 0;
