Principles of Object-Oriented Programming

Explore the fundamental principles of object-oriented programming in C++. Learn how encapsulation, abstraction, inheritance, and polymorphism organize and simplify code, enabling modular, reusable, and scalable software development.

We'll cover the following...

Introduction

Object-oriented programming (OOP) is a programming style that uses “objects” to design software. Imagine objects as real-world entities like cars, people, or even numbers. In object-oriented programming (OOP), these objects have attributes (properties) and methods (behaviors). For example, a car object might have attributes like color, make, and model, and methods like starting, stopping, and accelerating.

How is it different from procedural programming?

Object-oriented programming (OOP) and procedural programming are two different programming paradigms. Procedural programming focuses on writing procedures or functions that operate on data. It follows a step-by-step approach, with the main emphasis on functions and the sequence of actions. In contrast, OOP focuses on objects that encapsulate both the ...
