Question

You've been hired to write a program! The customer knows in general what he wants, but is going to rely on you to handle the technical details. He wants a program that can draw shapes on the screen, as many as he wants, in any order, and any size he wants. The shapes will include Square, Rectangle, Triangle, and optionally (a Challenge) Pyramid, like this:

****** ** * *
****** ** ** ***
*** *****

How do you find out what the user wants drawn?
How do you find out how big the drawing should be?
How will arrays be used, if you use them?
How will the switch statement be used, if you use it?
How will functions be used?
How will const be used?
