Question

Which following is one of the basic characters of object-oriented systems : Select one: a. process b. data c. module d. inheritance e. garbage collection

Answer 1

The answer is D.

Inheritance means that a child class (subclass) can inherit functionality from a parent class (superclass). For example, a class called Person could have 2 subclasses called Student and Teacher. While Student and Teacher have attributes and methods that differ, they also have some that overlap. By passing these overlapping functionalities down from the Person class, we are making the code more reusable. This eliminates the need to write duplicate code and makes the code more readable.
