Cpp Coding Standards

Enforces modern C++ practices based on the Core Guidelines, covering RAII, smart pointers, const correctness, and the Rule of Zero/Five. Use it when writing new C++ code or reviewing pull requests to catch things like raw new/delete, missing override keywords, or returning pointers to locals. The cross-cutting principles section is especially useful because it connects dozens of specific rules back to six core ideas like immutability by default and type safety. The parameter passing guide alone (cheap types by value, expensive by const ref) will save you from common performance mistakes. If you're still debating whether to use unique_ptr or shared_ptr, this makes the answer obvious.

C++ Coding Standards (C++ Core Guidelines)

Comprehensive coding standards for modern C++ (C++17/20/23) derived from the C++ Core Guidelines. Enforces type safety, resource safety, immutability, and clarity.

When to Use

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)

When NOT to Use

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)
