This lab has been designed for you to practice implementing and testing overloaded operators for a Rectangle class. The $05\_$Rectangle project contains the following Rectangle class in the "Rectangle. $h"$ file.

class Rectangle $\{$

private:

unsigned width, length$\_$;

public:

Rectangle$()$;

$(1)$ Mutator

void setwidth$($unsigned$)$;

void setLength$($unsigned$)$;

Accessor

double area$()$ const;

string to$\_$string$()$ const;

The width$\_$ and length$\_$data members represent the width and length of a Rectangle shape.

You are given the following member functions:

The default constructor sets the width and length of a new Rectangle object to $5$ and $10,$ respectively.

A setwidth member function that takes one parameter and updates the width of the invoking Rectangle object using the value of the parameter.

A setLength member function that takes one parameter and updates the length of the invoking Rectangle object using the value of the parameter.

An area member function returns the area of the invoking Rectangle object.

A to$\_$string member function returns a string that includes the width and length of the invoking Rectangle object.

In part I, you are asked to overload some operators for the Rectangle class using member functions. Make sure to write their prototypes in the "Rectangle. $h"$ file, implement them in the "Rectangle.cpp$"$ file, and test them in the "main.cpp$"$ file.
