Comprehensive coding standards for modern C++ (C++17/20/23) derived from the C++ Core Guidelines. Enforces type safety, resource safety, immutability, and clarity. Writing new C++ code (classes, functions, templates) Reviewing or refactoring existing C++ code Making architectural decisions in C++ projects Enforcing consistent style across a C++ codebase Choosing between language features (e.g., enum vs enum class, raw pointer vs smart pointer) Non-C++ projects Legacy C codebases that cannot adopt modern C++ features Embedded/bare-metal contexts where specific guidelines conflict with hardware constraints (adapt selectively) These themes recur across the entire guidelines and form the foundation: 1. RAII everywhere (P.8, R.1, E.6, CP.20): Bind resource lifetime to object lifetime 2. Immutability by default (P.10, Con.1-5, ES.25): Start with const/constexpr; mutability is the exception 3. Type safety (P.4, I.4, ES.46-49, Enum.3): Use the type system to prevent errors at compile time 4. Express intent (P.3, F.1, NL.1-2, T.10): Names, types, and concepts should communicate purpose 5. Minimize complexity (F.2-3, ES.5, Per.4-5): Simple code is correct code 6. Value semantics over pointer
