In GNU C, you may use C++ style comments, which start with ‘<samp><span class="samp">//</span></samp>’ and
|
||
|
|
continue until the end of the line. Many other C implementations allow
|
||
|
|
such comments, and they are included in the 1999 C standard. However,
|
||
|
|
C++ style comments are not recognized if you specify an <samp><span class="option">-std</span></samp>
|
||
|
|
option specifying a version of ISO C before C99, or <samp><span class="option">-ansi</span></samp>
|
||
|
|
(equivalent to <samp><span class="option">-std=c90</span></samp>).
