C/C++ Guide

Applies to: C++20, Systems Programming, Embedded, Game Engines, High-Performance Computing

Core Principles

1. RAII Everywhere: Every resource (memory, files, locks, sockets) is owned by an object whose destructor releases it
2. Zero Raw Ownership: Never use new/delete directly; use smart pointers and containers for all heap allocation
3. Value Semantics by Default: Pass and return by value; rely on move semantics and copy elision for performance
4. Compile-Time over Run-Time: Use constexpr, static_assert, concepts, and templates to catch errors at compile time
5. Warnings Are Errors: Build with -Wall -Wextra -Wpedantic -Werror; every warning is a latent bug
