I need to write a program for an analog clock with graphics of the face, numbers, and hands. I am so confused. I know that this is the current time, how do I do it with the graphics to show the face?

#include <time.h>
#include <stdio.h>

 void main()
   {
     time_t t; // correction
     time( &t );
     puts( ctime( &t ));
   }

This has hour, minute, and second hand. No numbers, but from the code, you may be able to finish the job.
    Hope this gets you started.   Good Luck!
