[Dev-C++] College Project

Hey guys, I'm an IT College Student and I need to make a project that contains looping, switching, decision, and basic input-output all in one. I understand the topics averagely, but I don't have any idea what to do. No idea comes to mind.  It's due tomorrow, the project was just given earlier today. I really need an idea. Maybe you could just reply with a problem and I will try to solve, that could help. Thanks.
