Answer :

Inheritance: The mechanism of deriving new class from an old/existing class is called inheritance.

OR

Inheritance is the process by which objects of one class acquired the properties of objects of another classes.


Syntax:

class derived-class-name: visibility-mode base-class-name

{

------//

-----// members of derived class

-----//

};


Types of inheritance: 

1) Single inheritance: In single inheritance, a derived class is derived from only one base class.

2) Multiple inheritance: In multiple inheritance, derived class is derived from more than one base classes.

3) Hierarchical inheritance: In hierarchical inheritance, more than one derived classes are derived from single class.

4) Multilevel inheritance: In multilevel inheritance, a derived class is derived from a derived class (intermediate base class) which in turn derived from a single base class.

5) Hybrid inheritance: Hybrid inheritance is a combination of single, multiple, multilevel and hierarchical inheritance.
