# C/C++ Formatting (clang-format)
`clang-format` is the de-facto C/C++ formatter. Like Prettier or rustfmt, it's deterministic and removes formatting debates.
## Prerequisites
- `clang-format` reachable — see "Is clang-format actually here?" below before concluding
it's missing; only then `brew install clang-format` / `apt install clang-format`.
- `.clang-format` config at project root (use `templates/cpp/.clang-format.tpl` if not present — `/cpp-init` drops it for you)
## Format changed lines only (preferred)
```bash
git diff -U0 --no-color HEAD | clang-format-diff -p1 -i
