Object-Oriented Programming Paradigm

• The major motivating factor in the invention of object-oriented approch is to remove some of the flaws encountered in the procedural approch.
• OOP treats data as a critical element in the program development and does not allow it to flow freely around the systems.
• It ties data more closely to the functions that operate on it, and protects it from accidental modification from outside functions.
• OOP allows decomposition of a problem into a number of entities called objects and then builds data and functions around these objects.
• The data of an object can be accessed only by the function associated with that object.
• However, functions of one object can access the the functions of other objects.

Some of the  striking features of object-oriented programming are

• 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.
• 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 approch in program design.
