What is object-oriented programming and how does it differ from functional programming?
Object-Oriented Programming (OOP) is a programming paradigm that models data as objects, each of which can have attributes and behaviors. Classes define objects and their behavior, and objects interact with each other through methods. OOP emphasizes encapsulation, inheritance, and polymorphism.

Functional Programming (FP) is a programming paradigm that emphasizes the use of functions to transform data. Functions are treated as first-class citizens, and the goal is to write pure functions that have no side effects and are deterministic. FP emphasizes immutability, recursion, and the avoidance of shared state.

In OOP, the primary unit of code reuse is the object and its behavior, while in FP, it is the function. OOP programs tend to be organized around objects that model real-world entities, while FP programs are organized around the transformations of data. OOP often employs a more imperative style, while FP uses a more declarative style.
