Create a simple program which uses the following class hierarchy:

Parent class: animal (should be an abstract class)

protected: String sound; // "moo", "quack", etc unsigned int number_of_legs;

Three different child classes: (three different specific animals)

Requirements:

Each class must have its own .cpp and .h file, including constructors and destructors.

Write a main function which creates instances of the three animals

Use the vector and Map classes in the main function to store multiple instances of the animals. Find a way to use these classes.

Create a polymorphic function called displayanimaldata which prints all the data within each animal. This is not a member function in any class.

void displayanimaldata(animal * a) { a->displaydata(); }

Initialize the instances and call the displayanimaldata function to test polymorphism of the displaydata function
