Object-Oriented Programming (OOP) is a programming paradigm that revolves around the concept of objects, which can contain data (attributes) and code (methods) that operate on that data. It aims to model real-world entities and their interactions, making software design more modular, reusable, and maintainable.

Key Characteristics / Core Concepts
- Objects: Instances of classes, representing real-world entities.
- Classes: Blueprints or templates for creating objects, defining their attributes and methods.
- Encapsulation: Bundling data and methods that operate on the data within a single unit (the object), hiding internal details.
- Inheritance: A mechanism where a new class (subclass) inherits properties and behaviors from an existing class (superclass).
- Polymorphism: The ability of objects of different classes to respond to the same method call in different ways.
- Abstraction: Hiding complex implementation details and showing only essential features.
How It Works / Its Function
OOP works by defining classes that serve as templates for objects. For example, a “Car” class might define attributes like `color` and `speed` and methods like `accelerate()` and `brake()`. When an object (e.g. `myRedCar`) is created from this class…
