using System;

/*Basic Geometry program

 As usual your program will ask the user for their name. [to be used throughout the porogram]

*Your program will run a menu an shown here.

Menu

1. Draw a Square

2. Draw a rectangle.

3. Exit the program

* if the user selects a [1] Square, you will ask the user for the length of one side of the square.

Then you will give them the Area and Perimeter for the selected length. (and draw the shape for them with the length shown on top)

after showing them that, you will go back to the Menu.

* if the user selects a [2] Rectangle, you will do exactly what you had done for "8th C# Program" you have just completed.

after showing them that, you will go back to the Menu.

* if they select [3] Exit, you will simply exit the program properly.

remember the user may run any of the Menu items as many times as they like.
