The keyword [[restrict|<code>restrict</code>]], though present in C, is not standard in C++, though some compilers may support it. The keyword <code>fortran</code>, a conditionally supported keyword in C which denotes linkage for the [[Fortran]] programming language, is conditionally supported in C++.

=== Alternative operator keywords ===

The following words are reserved keywords, but are used as alternative spellings for operators and tokens that use non-ISO646 characters.

{{div col|colwidth=15em}}
