Answer
Encapsulation is a mechanism that binds together code and the data it manipulates. It keeps them both safe from the outside world, preventing any unauthorised access or misuse. Only member methods, which are wrapped inside the class, can access the data and other methods.

Object Oriented Programming is an approach to standarise the program by creating partitioned memory area for both data and functions. It does not allow data to flow freely from one function to other. In this system, the complete problem is decomposed into a number of entities called objects. Some of the object oriented principles are given in the box as below:
Polymorphism Encapsulation Inheritance Abstraction Pick an appropriate principle for each of the descriptions given below:
(a) It allows deriving a new class from existing class. The new class will have combined features of both the classes.
(b) It promotes function overloading which is using a number of functions/methods with the same name but with different parameters.
(c) It allows grouping or merging data and functions as a unit such that the data of a particular object is used in the associated functions.
(d) It is using some external components without knowing the internal mechanism.
In assembly language, the instructions are given in terms of 0's and 1's.
