CCC-Assignment 12 Rectangle Solved

Below is some code for a rectangle class that needs to be completed. Add member function declarations to the class 
declaration and member function definitions below the declaration. For the accessor functions, you can add the definitions 
directly into the class declaration The goal is to code the class so that it works wthout changing the main program. 
You can cut and paste the code into a file (rectangle.cpp) in the Mimir IDE or any other environment where you can build and 
test the code more easily.
