Full form of OOP is Object Oriented Programming

A programming approach that structures software design around objects rather than functions or procedures. These objects represent real world entities and combine data with the methods that operate on that data. Core principles include encapsulation, inheritance, and polymorphism, which help organize complex systems into manageable and reusable components.

This approach is widely used in software development across applications ranging from web platforms to enterprise systems and mobile apps. Languages such as Java, C++, and Python support this model, making it a foundational concept for developers and computer science students. It allows teams to build scalable systems by promoting modular design and reducing code duplication.

Its importance lies in improving maintainability and clarity in large codebases. By modeling problems in a structured and intuitive way, it enables developers to extend and modify software with fewer side effects, making it a preferred paradigm in professional software engineering environments.
