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, you have to implement these classes with the following characteristics:

• Mammal class:

  • Has one protected variable for age of the mammal.

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

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

  • Function Speak() that displays “Mammal speaks mammalian!!”.

  • Function get_Age() which returns the age of the mammal.

• Dog class:

  • Inherits all the members from Mammal class.

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

  • Eat() should display “Dog eats meat”.

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

  • get_Age() should return Dog’s age.

• Cat class:

  • Inherits all the members from Mammal class.

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

  • Eat() should display “Cat eats meat”.

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

  • get_Age() should return Cat’s age.
