Question

Why do we use user defined classes?

(a) To design a user intended code

(b) To model real world objects

(c) To design the interfaces

(d) To model the functions

I have been asked this question in examination.

Query is from Class Use topic in chapter Classes of Object Oriented Programming

Answer 1

Correct choice is (b) To model real world objects

The best explanation: The primitive classes are not sufficient for the programming complex algorithms. Some user defined classes are required to represent a real world object and to define a blueprint of what the class should actually contain. The user defined classes are as per the requirements and need of user.
