In this assignment, you are going to use classes to solve a given problem. Think of the solution from an Object Oriented point of view where you are designing classes that communicate with each other to achieve a specific task, which would be the solution to the given problem$).$

Assignment Problem

A company wants to be able to display different mathematical shapes on the screen. Some of the shapes they are looking for are listed below:

A diamond

A triangle

A circle

A rhombus

The functionality of each shape is defined in a class. Each class contains the following functions:

DisplayShape$()$: This function displays the shape for that class

DisplayArea$()$: This function displays the area of that class

All classes you create need to inherit the following abstract class:

class Shape

$\{$

public:

virtual void DisplayShape$()=0$;

virtual void DisplayArea$()=0$;

$\}$;

Feel free to add whatever you want to the class you declare $($functions or attributes$),$ but you may not modify the Shape class.

The Task

From the list above, select $2$ shapes and create a class for each shape. Make sure in your class, you provide a way to set the member variables, which can be done in the constructor or by creating setter functions. Use the main$()$ function to test your code by creating objects$/$instances for each shape you decide to program. Make sure your main test both DisplayShape and DisplayArea functions.

Hint

If you were to create a Rectangle class that would use the Shape abstract class, you would have something similar to the following:

class Rectangle

$\{$

public:

void DisplayShape$()$;

void DisplayArea$()$;

$\}$;

void Rectangle::DisplayShape$()$

$\{$

$\}$

void Rectangle::DisplayArea$()$

$\{$

$\}$

void main$()$

$\{$

Rectangle R;

R$.$DisplayRectangle$()$;

R$.$DisplayArea$()$;

$\}$
