Exercise 3: Displaying Message Using Virtual Functions

Problem statement

We will first build three classes: Mammal (parent class), Dog (derived class) and Cat (derived class). The Dog and Cat class will inherit from Mammal.

In the exercise, implement these classes with the following characteristics:

• Mammal class:

  • Has one protected variable for the age of the mammal.

  • A constructor that takes the age of a mammal as input and sets it.

  • The function Eat() that displays Mammal eats food.

  • Speak() function that displays Mammal speaks mammalian!!.

  • get_Age() function that returns the age of the mammal.

• Dog class:

  • Inherits all the members from the Mammal class.

  • Implement all member functions of the Mammal class for the Dog class.

  • Eat() should display Dog eats meat.

  • Speak() should display Dog barks: ruff! ruff!.

  • get_Age() should return the dog’s age.

• Cat class:

  • Inherits all the members from the Mammal class.

  • Implement all member functions of the Mammal class for the Cat class.

  • Eat() should display Cat eats meat.

  • Speak() should display Cat meows: Meow! Meow!.

  • get_Age() should return the cat’s age.
