C# source code please and thank you:

Tasks This lab has four parts:

1. Write an abstract GeometricObject class.

2. Implement the Comparable and Cloneable interfaces into the abstract class.

3. Write an Octagon class that inherits from GeometricObject.

4. Write a program that creates an Octagon, and clones and compares the original to the clone.

Task 1 The GeometricObject Abstract Class First, let us make a simple abstract class titled GeometricObject. A GeometricObject should include: a side length attribute and an area attribute, a ToString method that returns both of the class variables AND the name of the class (which should be GeometricObject). It SHOULD NOT include any type of constructor. The variables should be made protected, but the methods should be public.

Task 2 Implementing the Comparable and Cloneable Interfaces Now implement the two interfaces by adding them to the class header. For Java: GeometricObject implements Comparable, Cloneable For C#: GeometricObject : IComparable, ICloneable We will also need to add two methods, one that comes from the Comparable class and one that comes from the Cloneable class. So we will override both the CompareTo and Clone methods so that they will compare two GeometricObjects and clone, or create a new, GeometricObject from an existing one. For the comparison, we will compare both of our objects values for side length and area. If both the side length and area are the same, then the method should return zero (0), otherwise if the values were greater than the originals values return negative one (-1), or return one (1) if the values were less than the originals values. For the clone method, it should return a new object with the same values as the original object it was cloned from.

Task 3 The Octagon Subclass Next is to create a class Octagon that inherits from our abstract GeometricObject class. This means it will also inherit the interface methods along with the class variables and any other defined methods or variables from GeometricObject. So the only thing we need to add is a constructor. The constructor should be a default constructor that sets the side length to eight (8) and calculates the area based on the side length. Also include an overloaded constructor that sets the side length to some input value, and uses that input value to calculate the area. Use the formula below for the area: Area = 2(1 + 2) * side^2

Task 4 The Driver (Main Program) Let us now use our classes by creating objects. Create an Octagon and clone it using the clone method from above. Now compare both the clone and the original using the compare method from above. Finally, print out the data stored in each object using their ToString methods and print out the result of the comparison (DO NOT explicitly call the ToString method when doing so). Below is some possible sample output (note: simply means, there exists): Some Sample Output: Octagon 1s side length: 8 and area is: 309.02 Octagon 2s side length: 8 and area is: 309.02 The 2 geometric objects are the same
