Base Class Vs. Derived Class: Explore the Difference between Base Class and Derived Class in C++
In the world of object-oriented programming languages, both base and derived classes play an important role. The base class is the existing class whereas the derived class is one that acquires the properties of a base class. There are many differences between them, let’s explore some major differences between a base class and a derived class.
What is a Base Class?
In an object-oriented programming language, a base class is an existing class from which the other classes are determined and properties are inherited. It is also known as a superclass or parent class. In general, the class which acquires the base class can hold all its members and some further data as well.
Syntax: Class base_classname{ … }.
What is a Derived Class?
A derived class is a class that is constructed from a base class or an existing class. It has a tendency to acquire all the methods and properties of a base class. It is also known as a subclass or child class.
Syntax: Class derived_classname : access_mode base_class_name { … }.
Difference between Base Class and Derived Class in C++
| S.No. | Base Class | Derived Class |
| 1. | A base class is an existing class from which the other classes are derived and inherit the methods and properties. | A derived class is a class that is constructed from a base class or an existing class. |
| 2. | Base class can’t acquire the methods and properties of the derived class. | Derived class can acquire the methods and properties of the base class. |
| 3. | The base class is also called superclass or parent class. | The derived class is also called a subclass or child class. |
