These guys are absolutely right. To take the example further, lets say you have this math expression:
Z=(A-(C*K))
when you parse this, it becomes
=
/ \
- Z
/ \
A *
/ \
C K
So parsing something really is about breaking it down into its individual chunks and pieces. For instance, a parser might break your c++ program into functions, or your word into letters. If you have a whole made of parts, the parser looks at those parts. Make sense? Check out the definitions linked above, they're probably better at explaining it than I am. Hope that helped a little.
PS The above is a "parse tree", certainly not the only way to parse or represent a parse. Just so you know.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
