Feature-Oriented Programming (FOP) is a programming paradigm that focuses on the modularization of software features. It allows developers to create software systems by composing various features, which can be independently developed and tested. This approach enhances code reusability and maintainability, making it easier to manage complex systems. In FOP, features are treated as first-class entities, enabling the dynamic combination of different functionalities. This is particularly useful in scenarios where software needs to be customized for different users or environments. By using FOP, developers can efficiently handle variations in software requirements while minimizing code duplication.
