Common Issues
| Issue | Solution |
|---|---|
| Formatting errors | Run clang-format -i <file> or let pre-commit fix it |
| Line too long | Break line at logical points, max 120 chars |
| Include order | Follow Google style: related header, C system, C++ standard, other libs, project headers |
Pre-commit hooks run automatically on commit. Fix any failures before pushing.
