Need H3lp With Simple Program

[IvoryGiant]

How would I add elements to create a menu at the end of the program asking to start the program over again?

[Mixelplik]

You should make each shape a function (or class) and then have a function with a menu, or main could have your menu.

or you could use a do while() loop.

[IvoryGiant]

How would the while() loop look in the program? Where would brackets be around?
