11# C++ Coding Style
12 
13> This file extends [common/coding-style.md](../common/coding-style.md) with C++ specific content.
14 
15## Modern C++ (C++17/20/23)
16 
17- Prefer **modern C++ features** over C-style constructs
18- Use `auto` when the type is obvious from context
19- Use `constexpr` for compile-time constants
20- Use structured bindings: `auto [key, value] = map_entry;`
21 
22## Resource Management
23 
24- **RAII everywhere** — no manual `new`/`delete`
25- Use `std::unique_ptr` for exclusive ownership
26- Use `std::shared_ptr` only when shared ownership is truly needed
27- Use `std::make_unique` / `std::make_shared` over raw `new`
28 
29## Naming Conventions
30 
31- Types/Classes: `PascalCase`
32- Functions/Methods: `snake_case` or `camelCase` (follow project convention)
33- Constants: `kPascalCase` or `UPPER_SNAKE_CASE`
34- Namespaces: `lowercase`
35- Member variables: `snake_case_` (trailing underscore) or `m_` prefix
36 
37## Formatting
38 
39- Use **clang-format** — no style debates
40- Run `clang-format -i <file>` before committing
41
