Which of the following is not true for Encapsulation?

1. Data and functions are loosely attached.
2. Data and functions are wrapped together.
3. Data is secured from getting mishandled.
4. None of them.

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:

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.

What is the literal meaning of Polymorphism?

1. Using different operations for same purpose
2. Using same operation for different purposes
3. Using same data in different functions
4. None of them

Which is not an Object Oriented Programming language?

1. Python
2. Eiffel
3. Small talk
4. COBOL
