🏛️ Object-Oriented Programming in C++

The four pillars and every OOP interview topic — with runnable code and animations.

A consolidated, runnable tour of object-oriented C++: the four pillars (encapsulation, abstraction, inheritance, polymorphism), access specifiers & inheritance modes, virtual dispatch and object slicing, abstract classes and interfaces, overloading vs overriding vs hiding, composition vs inheritance, and upcasting/downcasting with dynamic_cast & RTTI. Seven verified in-browser examples plus embedded animations and links to every deep-dive lesson.
