Assignment 5 - Rectangle Class

Read through Chapter 6 in your textbook before starting this assignment.

Write a class called Rectangle that represents a rectangle as a pair of floating-point values - the rectangle length and width. The data members of the class should be private members. Your class should include the following public functions:

a constructor that allows the client code to specify the initial values for the rectangle length and width. If the length or width is invalid (less than 0), set both length and width to 0.
a default constructor that sets the rectangle length and width to 0.0.
a "set" function that allows the client code to set the rectangle length and width. If the length or width is invalid (not larger than 0), set both length and width to 0.
a function that returns the length of the rectangle
a function that returns the width of the rectangle
a function that returns the area of the rectangle (length times width)
a function that returns the perimeter of the rectangle (2 times length plus 2 times width)

Write a small client program to test your class. Be sure that your client code calls each of the class functions and prints enough information to show that the class functions work correctly.

Note: Do not use global variables in your program (global constants are okay). Your Rectangle class should only have 2 data members - the length and width.

Note: You can code your class specification, the class implementation, and your client program in the same file.
