Lec-13 || Nesting of Classes || Aggregation || Composition || Constructors in Derived class.

In this lecture, we explore some advanced and important object-oriented programming concepts:

✅ Nesting of Classes – Learn how to define a class within another class and when to use it.

✅ Aggregation – Understand how to represent "Has-A" relationships between classes while keeping them loosely connected.

✅ Composition – Dive into tightly-bound object relationships where one class cannot exist without the other.

Each topic is explained with real-life analogies and C++ examples to make it super easy to understand for beginners and B.Tech students.

🎯 Perfect for last-minute revision before your semester exams!
