Regarding language version support for C++ and C, since GCC 11.1 the default target is ''gnu++17'', a superset of [[C++17]], and ''gnu11'', a superset of [[C11 (C standard revision)|C11]], with strict standard support also available. GCC also provides experimental support for [[C++20]] and [[C++23]].<ref>{{Cite web|title=C++ Standards Support in GCC|url=https://gcc.gnu.org/projects/cxx-status.html|access-date=May 17, 2021|archive-date=April 20, 2022|archive-url=https://web.archive.org/web/20220420114133/https://gcc.gnu.org/projects/cxx-status.html|url-status=live}}</ref>
