This is the heart of the book. Moving beyond procedural coding, the text demystifies Object-Oriented Programming (OOP). Concepts such as Encapsulation, Inheritance, Polymorphism, and Abstraction are explained not through heavy academic jargon, but through diagrams, memory maps, and real-world analogies. The distinction between a Class (the blueprint) and an Object (the instance) is made vividly clear, setting the stage for advanced design thinking.
