<a name="index-expressions-in-C-or-C_002b_002b"></a>

<p>Since C and C<tt>++</tt> are so closely related, many features of <small>GDB</small> apply
to both languages.  Whenever this is the case, we discuss those languages
together.

<p>The C<tt>++</tt> debugging facilities are jointly implemented by the C<tt>++</tt>
compiler and <small>GDB</small>.  Therefore, to debug your C<tt>++</tt> code
effectively, you must compile your C<tt>++</tt> programs with a supported
C<tt>++</tt> compiler, such as <small>GNU</small> <code>g++</code>, or the HP ANSI C<tt>++</tt>
compiler (<code>aCC</code>).
