Object-Oriented Programming: Core Principles and C# Implementation
TL;DR: Encapsulation: Keep data and logic together, hide internals behind clean interfaces Abstraction: Expose only what matters, hide the messy details Inheritance: Reuse common behavior by deriving from base classes Polymorphism: Write flexible code that works across types sharing a contract Introduction Ever wondered why most modern programming languages are object-oriented? It’s not just a trend; OOP completely changed how we think about building software. Object-Oriented Programming (or OOP, as we’ll call it) burst onto the scene in the 1990s and turned traditional programming on its head. Before OOP came along, most developers wrote procedural code, essentially a series of steps for the computer to follow, like a cooking recipe. While that worked for simpler programs, it became unwieldy as software grew more complex. ...
