Overview of oops

OOPS (C++)

What is object-oriented programming (OOP) system?

· OOP does not allow the data to flow freely around the system.

· OOP allows breakdown of a problem into a number of entities called objects.

· OOP builds data and functions around the objects.

· Private data become hidden and cannot be accessed by external function.

· Different objects may communicate with each other through function.

· OOP can be define as – “Object-oriented programming is an 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 as per requirements”.

Features of object-oriented programming

· It depend on data rather than procedure.

· Programs are divided into the objects.

· Functions that operate on the data of an object are joined together in the data structure.

· Private data is hidden and cannot be accessed by the external functions.

· Different objects may communicate with each other through function.

· Whenever needed, new data and functions can be easily added .

· Follow bottom-up approach in program design.
