Object-oriented programming (OOP) is a programming paradigm that focuses on organizing code into objects that encapsulate data called an attribute and behavior called a method. OOP is based on the concept of real-world entities or abstract concepts represented as objects, and the relationships among objects.
Objects are created from classes, which are templates that define the structure and behavior of objects. Classes encapsulate data in the form of attributes or properties, and behavior in the form of methods or functions. Objects are instances of classes, and they can interact with each other by invoking methods or accessing properties.
OOP is widely used in many programming languages, including C++, Java, Python, C#, and many others. It provides a modular and organized approach to software development, promoting code reusability, maintainability, and scalability. However, mastering OOP concepts and applying them effectively in software design requires practice and understanding of the underlying principles.
