<h1>Comments</h1>
<p>Comments are lines in a source file that have been marked to be ignored by the compiler.
Two styles of comments are supported by current C/C++ compilers:</p>
<ul>
<li><samp>/* text */</samp></li>
<li><samp>// text</samp></li>
</ul>

<h3>Comment</h3>
<p>You can quickly comment out one or more lines of code by inserting the leading 
characters <samp>//</samp> at the beginning of the line.  To do so, select the line 
(or lines) of code you want to comment out and press <b>CTRL+/</b> (slash).</p>

<h3>Uncomment</h3>
<p>To uncomment  select the line (or lines) of code, and press <b>CTRL+\</b> 
(backslash).

<p><b>Tip:</b> The characters <samp>/* */</samp> on lines that are 
already commented out, are not affected when you comment and uncomment code.</p>

<h3>Multiline comment</h3>
<p>You can use the Content Assist feature to insert a multi-line comment before a function.
Type <tt>com+Ctrl+Space</tt>, and the following code is entered at the cursor location:
<br><pre>
/*
 * author userid
 *
 * To change this generated comment edit the template variable "comment":
 * Window > Preferences > C/C++ > Editor > Templates.
 */
 </pre>

 To change the default comment click <b>Window > Preferences > C > Templates</b>.  For more information see the
