Hello and welcome back! Today, we're diving into the principles of Object-Oriented Programming (OOP) in C++ — Encapsulation, Abstraction, Polymorphism, and Composition — to enhance code readability and structure. Let's embark on this thrilling coding journey!

OOP principles provide the framework for creating readable, maintainable, and flexible code. These are the characteristics we aspire to during refactoring. By organizing properties and behaviors into logical class structures, we develop a codebase that's easier to understand and modify. This will become clearer as we move forward.

Encapsulation is about bundling related properties and methods within a class, thereby creating an organized structure that mirrors the real world.

Suppose we have scattered student information within our program.

This functional code can become confusing as related attributes and behaviors aren't logically grouped. Let's encapsulate!
