Programming Concepts class

The class is in the third week, so unfortunately I am playing catch-up. I am one who learns best by example, so I thought maybe if I can get help with the following program, then I will be able to catch up a lot faster. Please keep in mind when doing this, this class is for the newbie, so no need for any fancy stuff. Thanks, hopefully this helps!
