How should I do this assignment?

I think C++ would be the best to use, but I don't have any clue on how to start this assignment.

It's due today, which I've no illusions I can do, I still need to do it. Too many tests at the same time have stopped me from getting an earlier start on it, and its been some time since I've programmed.
I just want to know how I should start this, including variables, methods, and classes. Any suggestions would be appreciated.

Err, is that C++?

A rough outline of what parameters needs to be in each thing would be excellent, or especially some good reference materials.
I haven't programmed in C++ in over 2 years, and don't know where to start.
