Some key features of the Object Oriented programming are:

â–º Emphasis on data rather than procedure

â–º Programs are divided into entities known as objects

â–º Data Structures are designed such that they characterize objects

â–º Functions that operate on data of an object are tied together in data structures

â–º Data is hidden and cannot be accessed by external functions

â–º Objects communicate with each other through functions

â–º New data and functions can be easily added whenever necessary

â–º Follows bottom up design in program design
