In GNU C, you may use C++ style comments, which start with //
and
continue until the end of the line. Many other C implementations allow
such comments, and they are likely to be in a future C standard.
However, C++ style comments are not recognized if you specify
-ansi
, a -std
option specifying a version of ISO C
before C99, or -traditional
, since they are incompatible
with traditional constructs like dividend//*comment*/divisor
.
