Lesson26and27

If you’re looking to sharpen up your C++ programming skills, then you’re in the right place. You will start with learning about dynamic memory allocation, how to create classes, and constructors. 

In the latter half of the course, inheritance, functions, I/O, exception handling, and more. Throughout the course, you will study over 90 carefully designed examples aimed to enhance your understanding of the C++ language.  

By the time you finish this course, you will be able to use more advanced functionality in your C++ programs.

C++ Programming for Experienced Engineers

# Challenge

Write a program that has 3 classes in it (`Shape`, `Cost`, and `Rectangle`). Of these, `Shape` and `Cost` should be independent classes, whereas `Rectangle` should be derived from `Shape` and `Cost`.
The `Shape` class should maintain shape type (*Plate* or *Ring*), *length* and *breadth* of the shape type. The `Cost` class should have a `getCost( )` function that returns the cost of polishing the shape based on the type of the shape. Assume that it costs **$50** per plate and **$22** per ring. 

The `Rectangle` class should contain a function `getQuantity( )` that returns the area if the shape type is a _plate_ and _perimeter_ if the shape type is a _rectangular ring_. Create objects of the `Rectangle` class in `main( )` and call `getQuantity( )` and `getCost( )` using these objects to determine the quantity and polishing of each.

# Sample run	 	 
Here’s what you should see when you run the program.                        
```txt
Shape type: plate with length = 10 and breadth = 20
Quantity = 200 and Cost = 10000

Shape type: ring with length = 2 and breadth = 3
Quantity = 10 and Cost = 220
```

# Coding exercise

Your job is to define a `Rectangle` class that is derived from two classes (`Shape` and `Cost`).

Understand multiple inheritance with an example of a derived Rectangle class.
