<h3 class="section">6.32 C++ Style Comments</h3>

<p><a name="index-g_t_002f_002f-2475"></a><a name="index-C_002b_002b-comments-2476"></a><a name="index-comments_002c-C_002b_002b-style-2477"></a>
In GNU C, you may use C++ style comments, which start with &lsquo;<samp><span class="samp">//</span></samp>&rsquo; 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>).
