Question

C++ ONLY PLEASE

Problem Description:

Objective: Create Inheritance Hierarchy to Demonstrate Polymorphic Behavior

Create a Rectangle Class

Derive a Square Class from the Rectangle Class

Derive a Right Triangle Class from the Rectangle Class

Create a Circle Class

Create a Sphere Class

Create a Prism

Class Define any other classes necessary to implement a solution

Define a Program Driver Class for Demonstration

a) Create a Container to hold objects of the types described above

b) Create and Add two(2) objects of each type described above

c) Compute the area, perimeter, and volume in a uniform manner for each object in the Container. Display the results. Note: perimeter is not defined for a 3D object and volume is not defined for a 2D object.

Document your code, tell me what you are doing, and make it readable. Creativeness and Quality Craftsmanship do count.
