Eclipse C/C++ Developer Guide

Comments

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:

  • /* text */
  • // text

Comment

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

Uncomment

To uncomment select the line (or lines) of code, and press CTRL+\ (backslash).

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

Multiline comment

You can use the Content Assist feature to insert a multi-line comment before a function. Type com+Ctrl+Space, and the following code is entered at the cursor location:

/*
 * author userid
 *
 * To change this generated comment edit the template variable "comment":
 * Window > Preferences > C/C++ > Editor > Templates.
 */
 
To change the default comment click Window > Preferences > C > Templates. For more information see the Content Assist section.
