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 selection and combination of features to tailor software to specific needs. This is particularly useful in domains like software product lines and configurable systems, where different configurations may be required for different users or environments.
