This version of the rectangle app shows how to create 3 instances
of the Rectangle class so we can find the total area of three rooms.
However, each Rectangle object we create holds different sets of data.
This data is stored with each object in memory.

Here we reuse our class to make our coding way easier!
We are resuing the same class three times. (Resuablity)
It is easier to maintain than a procedural version. (Maintainability)
It can be extended (Extensibility) by simply adding another class for
and entire house.

//Step 1: Add a new class to the project called Rectangle and make it inline.
//Step 2: In this file, add an include "Rectangle.h" directive so we can access it.

//Run with CTL-F5

#include "stdafx.h"
#include <iostream>
#include <iomanip>				//so we can format our output
#include "Rectangle.h"			//the class you just made
