How to Create Pet, Dog, and Rock Classes in C++

What are the key features of the Pet, Dog, and Rock classes in C++?

Can you explain how the classes are structured and what functions are defined?

Key Features of Pet, Dog, and Rock Classes in C++

The Pet class in C++ stores the pet's name, age, and weight, with appropriate constructors, accessors, and mutator functions for these attributes. It also defines a function called getLifespan that returns "unknown lifespan."

The Dog class, which is derived from the Pet class, introduces a private member variable named breed to store the breed of the dog. It includes mutator and accessor functions for the breed variable and has constructors for initialization. The getLifespan function is redefined to return "approximately 7 years" if the dog's weight is over 100 pounds, and "approximately 13 years" if the dog's weight is under 100 pounds.

On the other hand, the Rock class, also derived from the Pet class, redefines the getLifespan function to return "thousands of years." This showcase the flexibility of inheritance and polymorphism in object-oriented programming.
