What exactly is your programming-related question, and the shortest code needed to reproduce said issue? I see a dump of what presumably is an assignment, but no question. See How do I ask and answer homework questions? and Open letter to students with homework problems tldr: we won't do your assignment for you, but if you have a specific issue we may be able to help with that — cocomac 40 secs ago
