Introduction & Core Concept

C++ is a high-performance compiled language that provides low-level memory control alongside powerful object-oriented and generic abstractions.

WHY DOES THIS MATTER IN THE REAL WORLD?

C++ powers game engines (Unreal Engine), operating systems (Windows, macOS kernels), database engines, and high-frequency trading platforms.
