“Click Here” Object-oriented programming (OOP) is a programming paradigm that promotes the use of objects to represent real-world entities and their interactions. It is vital in computer science as it provides a structured and modular approach to software development. OOP emphasizes concepts like encapsulation, inheritance, and polymorphism, making code more organized, maintainable, and reusable. OOP fosters the development of large-scale, complex software systems, enhances code reusability, and simplifies collaborative coding efforts. A solid grasp of OOP principles is essential for software engineers and developers to create well-structured and scalable applications.
