Object oriented programming uses inheritance, where a derived class inherits properties from a base class. There are four main types of inheritance: single inheritance where a derived class has one base class; multiple inheritance where a derived class has multiple base classes; multilevel inheritance where a class inherits from another derived class; and hierarchical inheritance where one base class is inherited by multiple derived classes. Inheritance enables code reuse and is a fundamental concept of object oriented programming.

3. INHERITANCE
 The mechanism of deriving a new class from an old
class is called inheritance.
 The old class is referred as base class and new
one is called as derived class.
 A new class inherits some or all properties from the
base class.
 Inheritance enables reusability.

5.  Single inheritance: a derived class with only one
base class is called single inheritance.
 Multiple inheritance: a derived class with several
base classes is multiple inheritance.
 Multilevel inheritance: the mechanism of deriving a
class from another derived class is known as
multilevel inheritance.
 Hiererchical inheritance: one class may be inherited
by more than one class is known as hierarchical
inheritance.
