Advantages and Disadvantages of Inheritance in C++
Looking for advantages and disadvantages of Inheritance in C++?
We have collected some solid points that will help you understand the pros and cons of Inheritance in C++ in detail.
But first, let’s understand the topic:
What is Inheritance in C++?
Inheritance in C++ is a feature that allows a derived class to inherit the properties and methods of a base class, promoting code reuse and reducing redundancy.
What are the advantages and disadvantages of Inheritance in C++
The followings are the advantages and disadvantages of Inheritance in C++:
|Abstraction||Violation of encapsulation|
Advantages of Inheritance in C++
- Code Reusability – Inheritance in C++ allows you to create new classes that are based on existing classes, so you can reuse existing code and avoid rewriting the same functionality. This can save a lot of time and effort when you’re creating new programs.
- Organization – Inheritance in C++ helps you organize your code in a logical and structured way. By creating classes that inherit from other classes, you can create a hierarchy of related classes that makes it easy to understand how your code works and how different parts of your program are related.
- Polymorphism – Inheritance in C++ allows you to create objects that can take on different forms, depending on the class they inherit from. This is called polymorphism, and it can make your code more flexible and adaptable to changing requirements.
- Overriding – Inheritance in C++ allows you to override methods in a derived class, which means you can change the way a method works without changing the original code. This is a powerful way to customize existing code to suit your needs.
- Abstraction – Inheritance in C++ allows you to create abstract classes that define the basic behavior of a group of related classes, while leaving the implementation details to the derived classes. This is called abstraction, and it can make your code more modular and easier to understand.
Disadvantages of Inheritance in C++
- Complexity – Inheritance in C++ can make your code more complex, especially when you have multiple levels of inheritance or when you’re inheriting from classes that have a lot of methods and properties. This can make it harder to understand how your code works and can lead to bugs and other issues.
- Rigidity – Inheritance in C++ can make your code more rigid, as it can be difficult to change the way a class works once it has been inherited by other classes. This can make it hard to adapt your code to changing requirements and can limit its overall flexibility.
- Dependency – Inheritance in C++ can create dependencies between classes, which can make it harder to reuse your code in other programs or to make changes to your code without affecting other parts of your program.
- Performance – Inheritance in C++ can impact the performance of your code, as it requires additional memory and processing power to maintain the relationship between classes. This can slow down your program and make it less efficient.
- Violation of encapsulation – When using inheritance, the child class gets access to the parent class’s private member variables, which can lead to unexpected changes, errors and can violate encapsulation principle. This can lead to bugs and other issues and can make it harder to maintain your code.
