1. INHERITANCE

2. INHERITANCE OOP allows class to create new classes which may have some common feature to the exiting classes this is achieved by inheritance. Inheritance is a process of creating new class from the existing class. The existing classes are called base class or super class and the inherited classes are called derived classes or sub class

3. Types of inheritance Single inheritance Multiple inheritance multi-level inheritance

4. Single inheritance In this case there is only 1 base and derived class and inheritance take place between them. For ex:- Class animal { Bones Legs hand } Class vertebrates { Bones Legs }
