This practical task introduces you to inheritance, a mechanism in which one class acquires the features and

behaviour of another class. The class whose features are inherited is known as a super class $($or a base class

or a parent class$).$ The class that inherits from the other class is known as a subclass $($or a derived class, or

an extended class, or a child class$).$ The subclass can add its own attributes and methods in addition to those

of the superclass. Inheritance supports the concept of $$reusability$.$ That is$,$ when we want to create a new

class and there is already a class that includes some of the code that we want, we can derive our new class

from the existing class. By doing this, we are reusing the attributes and methods of the existing class.
