Object Oriented Programming

158 - Write a program that models a real-world object as a class and implements inheritance, encapsulation, and polymorphism concepts. For example, you can create a class for a car, which has properties such as make, model, and year, and then inherit from that class to create a class for a sports car, which adds a property such as top speed.
