Is C++ Object-Oriented Programming?


Larry Thompson

In the world of programming, there are a wide variety of languages to choose from, each with its own unique features and qualities. One such language is C++, which has been widely used for several decades.

But is C++ truly an object-oriented programming language? Let’s dive in and explore this question.

Understanding Object-Oriented Programming

Before we can determine whether C++ is object-oriented or not, let’s first clarify what object-oriented programming (OOP) entails. OOP is a programming paradigm that revolves around the concept of objects. Objects are instances of classes, which are essentially blueprints for creating these objects.

OOP emphasizes the organization of code into reusable and modular components. It promotes encapsulation, inheritance, polymorphism, and abstraction as key principles for designing software systems. By organizing code into classes and objects, OOP allows developers to create more maintainable and scalable applications.

The Object-Oriented Features of C++

C++ was developed as an extension to the popular C programming language. It introduced several features that align it closely with object-oriented principles:

  • Classes: C++ allows developers to define classes, which serve as the blueprints for creating objects. Classes encapsulate data (member variables) and behavior (member functions) into a single entity.
  • Inheritance: Inheritance enables the creation of new classes based on existing ones.

    This feature promotes code reuse and hierarchical structuring of classes.

  • Polymorphism: Polymorphism in C++ allows objects of different classes to be treated interchangeably if they share a common base class. This promotes flexibility and extensibility in software design.
  • Abstraction: C++ supports abstraction through the use of abstract classes and pure virtual functions. Abstract classes cannot be instantiated directly but serve as base classes for other classes.

These features demonstrate that C++ incorporates fundamental concepts of object-oriented programming, making it possible to design and implement object-oriented systems.

C++ Beyond Object-Oriented Programming

While C++ has strong ties to object-oriented programming, it is important to note that it is not limited to this paradigm. C++ also supports procedural programming, generic programming, and even low-level programming constructs.

In addition to its object-oriented capabilities, C++ provides features like function pointers, templates, and direct memory manipulation. These features allow developers to write code in a procedural or generic style when necessary.


In conclusion, despite its roots in the procedural programming language C, C++ has evolved to become a versatile language capable of supporting object-oriented programming. It incorporates key features like classes, inheritance, polymorphism, and abstraction that are essential for designing and building object-oriented systems.

However, it’s worth noting that C++ is not limited to just object-oriented programming. It offers flexibility by supporting other paradigms like procedural and generic programming as well.

C++ remains a popular choice for developers due to its powerful combination of features from various paradigms. Whether you choose to use it in an object-oriented manner or explore its other capabilities is ultimately up to you as a programmer.
