What is OOP?

Object-oriented programming (OOP) is a programming paradigm based on "objects", which contain data in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods). A common feature of objects is that procedures (methods) are attached to them and can access and modify the object's data fields. Objects are used to interact with one another to design applications and computer programs. OOP is commonly used for creating complex software systems, providing modularity, reusability, and maintainability of code.
