Inheritance in Object Oriented Programming
Download as PPTX, PDF•1 like•2,326 views
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. TYPES OF INHERITANCE
