2. What is OOP? Object Oriented Programming (OOP) is a programming technique in which programs are written on the basis of objects. Examples: C++ PHP Java

3. Classes(Classification Of Objects) A class is a group of objects with same attributes and behavior. A class is user define derived class that combines both data and function and function and manipulate the data. Object  is a class type variable.  Objects  are also called instance of the class. Each  object  contains all members(variables and functions) declared in the class : Identity State Behaviour What is Object?

4. Benefits Of OOP Reusability Extensibility Decomposability Compos ability Understandability Security Characteristics Of OOP Inheritance Data Abstraction Data Encapsulation Polymorphism

5. Inheritance A programming technique that is used to reuse an existing class to build a new classis known as inheritance. Categories Of Inheritance 5 levels of inheritance - -Single level -Multilevel -Multiple -Hierarchical -Hybrid

6. Data Abstraction Data abstraction or information hiding refers to providing only essential information to the outside world and hiding their background details. Advantages Of Data Abstraction Simplification of software development. Testing and debugging. Reusability. Security. Modifications to the representation of a da ta type.

7. Data Encapsulation Data Encapsulation is an Object Oriented Programming concept that binds together the data and functions that manipulate the data and that keep both safe from outside interference and misuse.

8. Polymorphism The word polymorphism is a combination of two words poly and morphism . Poly means many and morphism means form. In object-oriented programming, polymorphism is the ability of objects of different types to respond to functions of the same name. The user does not have to know the exact type of the object in advance. The behavior of the object can be implemented at run time. Types Of Polymorphism Virtual functions. Operator overloading. Function overloading
