C++ Programming - OOPS Concepts - Discussion

Thank you @Harjot.

It can acquire the properties of another class so, inheritance provides reuse mechanism.

easy to test

Why not Abstraction?

Inheritance allows the programmer to make use of the features of one class to make another sub-class. For example, 'Pigeon' reuses or inherits some features from the class 'Bird'.

Abstraction is said to be in effect when the user is provided with only the useful information, hiding the rest. For instance, a user doesn't need to know how the class 'Pigeon' is stored in the memory - all s/he cares about it how different is 'Pigeon' from 'Peacock'.

Encapsulation allows us to wrap data and functions that will use that data, into a single unit such as a Class. A class for creating a 'Bird' would have all the data and the functions related to this class.

Polymorphism is the property by which any entity can behave differently when a different message is passed to them. One set of parameters in the class 'Bird' can you a 'Pigeon', another can give you a 'Peacock'.

Through inheritance, we can acquire the properties of the parent class. Thus we can reuse the methods and variables of the parent class.
