Question

Use the Animal class file given on the final exam module.

Use Inheritance and Polymorphism concepts to create the following classes and functions.

Create the following classes that derive from the Animal class.

Monkey
Kangaroo

Create a derived class named Spider Monkey whose base class is Monkey.

Create constructors for each class.
Create destructors for each class.
All classes will have the following private instance fields, including Animal

legs that will initialize to 0
boolean swim that will initialize to false;

All classes will have the following polymorphic methods, including Animal

getLegs( ) – this returns the number of legs the animal has
makeSount( ) – this outputs the type of sound the animal makes

makeSound( ) method will be a virtual function in the Animal class
Create an exception in the getLegs( ) method that makes sure the number of legs are valid (only allow positive number amount of legs)
Create a main method to demonstrate the all functions including the following with appropriate output

Animal animal;

animal.makeSound();

Monkey monkey;

monkey.makeSound();

cout << monkey.getLegs();

Animal badMonkey = Monkey();

badMonkey.makeSound();

cout << badMonkey.getLegs();

Animal* goodMonkey = new Monkey();

goodMonkey->makeSound();

cout << goodMonkey->getLegs();

Animal* goodKanga = new Kangaroo();

goodKanga->makeSound();

cout<<goodKanga->getLegs();
