CPP

What is CPP

C++ is the primary programming language used throughout the Source engine and its toolchain. It is a compiled, statically-typed language that offers high performance and fine-grained control over memory and system resources making it ideal for game engine development.

C++ supports multiple programming paradigms, including procedural, object-oriented, and generic programming. It introduces features such as classes, inheritance, virtual functions, and templates, all of which Valve used extensively in Source to build complex, modular systems.

Most engine code, game logic, tools, and extensions in Source are written in C++. Familiarity with the language is essential for working with the Source SDK, modifying game .dlls, or creating new engine features.
