Object-Oriented Programming for MAANG Interviews

A book-shaped table of contents for OOP: paradigm foundations, the four pillars, object relationships, SOLID/GRASP design principles, memory and runtime internals, GoF design patterns, language-specific OOP, and OOP at system scale — cross-linking existing pattern, concurrency, and low-level-design notes instead of duplicating them.

2 — Why OOP Exists

Surveys Software Complexity, Code Reusability, Maintainability, Real-world Modeling, Separation of Concerns, and Abstraction vs Implementation as the core sub-topics of why oop exists.

3 — Objects and Classes

Surveys Objects, Classes, State, Behavior, Identity, Object Lifetime, and Object Relationships as the core sub-topics of objects and classes.

4 — Polymorphism

Explains Compile-Time Polymorphism, Runtime Polymorphism, Method Overloading, Method Overriding, Virtual Functions, Dynamic Dispatch, VTables, and Late Binding as the core sub-topics of polymorphism.
