Help with a program.

[Breakthrough]

Yes, this is for homework. Well I need help on creating a menu. I want to create it using either switch, or a while if. I want it to display as:

1)  Classify Your Triangle.
2)  String That Does Nothing.
3)  Cash Register Receipt.
4)  Quadratic Formula.
5)  End Program.

Now I want it so that when an option is chosen, and that part of the program it completes, it goes back to the original menu so that you can choose 1 to 5 over again. Also, I would prefer if a goto was not used because it does not seem to be working very easily.
