Hey, thanks for the report. The anysphere.cpptools extension doesn’t provide formatting functionality. It uses the built-in clangd for language features.

For formatting C/C++ files, I recommend installing a separate Clang-Format extension: Open VSX Registry

After installing it, you can set the path to your preferred clang-format version via the clang-format.executable setting.
