C++ Coding Style

This file extends common/coding-style.md with C++ specific content.

Modern C++ (C++17/20/23)

• Prefer modern C++ features over C-style constructs
• Use auto when the type is obvious from context
• Use constexpr for compile-time constants
• Use structured bindings: auto [key, value] = map_entry;

Resource Management

• RAII everywhere — no manual new/delete
• Use std::unique_ptr for exclusive ownership
• Use std::shared_ptr only when shared ownership is truly needed
• Use std::make_unique / std::make_shared over raw new

Naming Conventions

• Types/Classes: PascalCase
• Functions/Methods: snake_case or camelCase (follow project convention)
• Constants: kPascalCase or UPPER_SNAKE_CASE
• Namespaces: lowercase
• Member variables: snake_case_ (trailing underscore) or m_ prefix

Formatting

• Use clang-format — no style debates
• Run clang-format -i <file> before committing
