Assigned 9/15/2017-Due 9/18/2017 at NOON Introduction: In this in class assignment, you will program a basic class for a rectangle. Here is what your class should include Private members length and width. Use the data type of double. . Default Constructor Overloaded constructor to accept length and width as arguments Public methods for . o Setting the length o Setting the width o Getting the length o Getting the width o Getting the area o Getting the perimeter In order to test your code, write a main function that Creates a first rectangle using the default constructor Sets the length and width of the first rectangle using the methods Displays the length, width, area, and perimeter of the first rectangle Creates a second rectangle using the overloaded constructor Displays the length, width, area, and perimeter of the second rectangle. Displays the sum of the perimeters Displays the difference between the areas . This submission MUST be done with 3 different files. Put the class definition in rectangle.h, the implementation of the methods in rectangle.cpp, and the main function in main.cpp. WRITE A MAKEFILE THAT WILL COMPILE THIS. In rectangle.h and rectangle.cpp, use comments to label your methods as either Constructors, Accessors or Mutators. Recommendations: .Get the class and implementations of the methods working in main.cpp. Once when your code is working, then worry about separating them into the different files
