  Introduction • OOP isan approach that provides a way of modularizing programs by creating partitioned memory area for both data and functions that can be used as templates for creating copies of such modules on demand. • This means that means that an object is considered to be partitioned area of computer memory that stores data and a set of operations that can access the data.

  Object-Oriented Paradigm • Someof the features of object oriented paradigm are: -  Emphasis is on data rather than procedure.  Programs are divided into what are known as objects.  Data structures are designed such a way that can characterize the objects.  Method that operates on the data of an object is tied together in the data structure.  Data is hidden and cannot be accessed by external function.  Object may communicate with each other through methods.  Follows bottom up approach in the program design.

  Basic Concepts ofObject-Oriented Programming  Object and classes  Data abstraction and encapsulation  Inheritance  Polymorphism • Dynamic binding • Message communication

  Benefits of OOP OOPSoffers several benefits to both the program designer and the user. Some of them are as follows:- • Software complexity can be easily managed. • Object oriented system can easily upgrade. • It is easy to partition data in the project on the basis of objects. • With the help of inheritance, we can easily eliminate redundant code and extend the use of existing code. • The principle of data hiding helps the programmer to build secure programs. • Message passing technique makes interface descriptions with external system much simpler.

  Application of OOP •Some of the application areas of OOPs is as follows: -  Real time systems.  Simulation and modeling  Object oriented databases  Hypertext, hypermedia and expertext  AI and expert systems.  CIM/CAD/CAD systems
