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.

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. Types of inheritance
