Characteristics of object-oriented programming:

•   Emphasis is on data rather than procedure.

•   Programs are divided into what are known as objects.

•   Data structures are designed such that they characterize the objects.

•   Functions that operate on the data of an object are tied together in the data structure.

•   Data is hidden and cannot be accessed by external functions.

•   Objects may communicate with each other through functions.

•   New data and functions can be easily added whenever necessary.

•   Follows bottom-up approach in program design.
