Question

What is inheritance? Explain with an example.

Answer 1

Inheritance is the process of creating a new class, called the derived class, from an existing class, called the base class. The derived class can use the data members and methods of the base class and may also add its own features.

Example: Mobile_phone can be a base class and i_phone can be a derived class. An iPhone has all common features of a mobile phone, such as model, colour and price, along with its own special features.

This represents an “is-a-kind-of” relationship: an iPhone is a kind of mobile phone.
