Object oriented programming is method of programming where a system is considered as a collection of objects that interact together to accomplish certain tasks. Objects are entities that encapsulate data and procedures that operate on the data.

In OOPS first a concept known as "Object oriented analysis(OOA)" is used to specify the objects in term of real world requirements, their behaviour and interactions required. The next concept would be the "Object oriented design(OOD)" that converts these realtime requirements as a hierarchy of objects in terms of software development requirement. Finally OOPS is used to implement the requirements using the C++ programming language.

The main purpose of object oriented programming is to simplify the design, programming and most importantly debugging a program. So to modify a particular data, it is easy to identify which function to use. To add additional features it is easy to identify where to add functions and its related data.

Following are the basic elements of Object oriented programming(OOPS)

• Object
• Classes
• Inheritance
• Dynamic Binding
• Polymorphism
• Message passing
• Encapsulation
