Question

(a) Make program more efficient

(b) Makes program execution faster

(c) Helps to add extra functionality to a function

(d) Helps to add more members to a function

This question was addressed to me by my school teacher while I was bunking the class.

Enquiry is from Local Class topic in section Class Members & Types of Object Oriented Programming

Answer 1

The correct option is (c) Helps to add extra functionality to a function

Easy explanation - The closest answer is to add more functionalities to a function or to make some specific functions to be generic. Adding more members to a function can be done directly but to add some special functionality that are encapsulated, can be done using local classes.
