Questions and Answers

What is the primary purpose of using inheritance in programming?

To enable the creation of more specific classes that share common traits. (correct)
To improve the performance of individual classes without any relation.
To define characteristics common to a group of unrelated entities.
To create a general class that has no specific function.

Which statement best describes a general class in the context of inheritance?

It contains unique characteristics that do not relate to other classes.
It serves as a template for defining common traits for related subclasses. (correct)
It is a final class that cannot be inherited by any other classes.
It can only contain methods but not attributes.

What is typically added by more specific classes that inherit from a general class?

All functionalities of the general class without enhancements.
Methods that override the inherited methods without retaining any features.
Additional characteristics that make them unique. (correct)
Characteristics that are common to all classes.

Study Notes

Inheritance in Programming

Inheritance is a core principle in object-oriented programming (OOP).
It allows for the creation of a general "parent" class that defines shared characteristics.
The "parent" class is also known as a base class or superclass.
Other, more specific "child" classes can inherit the characteristics of the parent class.
These child classes are also known as derived classes or subclasses.
Child classes can add their own unique characteristics on top of the inherited ones.
This promotes code reusability and a hierarchical structure in software design.
