What is Single Inheritance?
Single inheritance is a fundamental concept in object-oriented programming (OOP) where a class inherits properties and behaviors from a single base class.

It allows the derived class to access the public and protected members of the base class.
By utilizing single inheritance, we can create a hierarchy of classes that share common characteristics, enabling code reusability and promoting modular programming.
Benefits of Single Inheritance in C++
Single inheritance offers several advantages when it comes to designing and implementing classes in C++.
Some of the key benefits include:
- Code Reusability: Single inheritance allows us to reuse the properties and behaviors defined in the base class, reducing code duplication and promoting a more efficient and modular codebase.
- Simplified Class Hierarchy: With single inheritance, the class hierarchy remains simple and easy to understand. Each derived class inherits directly from a single base class, leading to a clearer and more maintainable code structure.
- Encapsulation and Abstraction: By inheriting from a base class, the derived class can encapsulate the common attributes and behaviors, abstracting away the implementation details and providing a higher level of abstraction.
- Polymorphism: Single inheritance sets the foundation for polymorphism, a powerful feature of OOP that allows objects of different classes to be treated uniformly through a common interface. Polymorphism enables flexibility and extensibility in our code.
Now that we have an understanding of single inheritance and its benefits, let’s explore how we can utilize it to perform the addition of two numbers in C++.

Addition of Two Numbers Using Single Inheritance in C++
To illustrate the addition of two numbers using single inheritance, let’s consider a scenario where we have a base class called Number
and a derived class called Addition
.

The Number
class will contain the basic properties and methods related to numbers, while the Addition
class will inherit from Number
and provide the functionality to add two numbers.
Here’s an example implementation:
#include <iostream>
class Number {
protected:
int num1, num2;
public:
void setNumbers(int n1, int n2) {
num1 = n1;
num2 = n2;
}
};
class Addition : public Number {
public:
int addNumbers() {
return num1 + num2;
}
};
int main() {
Addition addition;
addition.setNumbers(5, 7);
int sum = addition.addNumbers();
std::cout << "The sum of the numbers is: " << sum << std::endl;
return 0;
}
In the above code, we define two classes: Number
and Addition
. The Number
class has a protected member num1
and num2
, which can be accessed by derived classes.
The setNumbers
function allows us to set the values of num1
and num2
.
The Addition
class inherits from Number
using the public
access specifier, enabling it to access the protected members.

The addNumbers
function calculates the sum of num1
and num2
and returns the result.
By creating an object of the Addition
class, setting the numbers using setNumbers
, and calling addNumbers
, we can obtain the sum of the two numbers.
Frequently Asked Questions
Single inheritance in C++ serves the purpose of enabling code reusability, promoting modular programming, simplifying class hierarchies, and facilitating encapsulation and abstraction. It allows a derived class to inherit properties and behaviors from a single base class, leading to cleaner and more maintainable code.
No, in single inheritance, a derived class can inherit from only one base class. However, C++ supports multiple inheritance, where a class can inherit from multiple base classes simultaneously.
Protected members of the base class can be accessed directly by the derived class. They are not accessible outside the class hierarchy but can be accessed by any derived classes.
Yes, in C++, you can override the base class methods in the derived class by redefining them with the same signature. This allows you to modify the behavior of the inherited method in the derived class.
Single inheritance allows a derived class to inherit from a single base class, whereas multiple inheritance allows a derived class to inherit from multiple base classes simultaneously. Single inheritance simplifies the class hierarchy and promotes a clearer code structure, while multiple inheritance offers more flexibility but can result in a more complex codebase.
No, C++ supports multiple types of inheritance, including single inheritance, multiple inheritance, hierarchical inheritance, and hybrid inheritance. Each type has its own characteristics and use cases.
