Good afternoon perl monks.
I have this question and I have come up with the code below so far but I cant get it to work.
This is the question: Write a Perl program that prints out all the even numbers from 0 to 20. Print this list 4 times, using while, until, do-until and for loops (so you need to use all 4 loop structures!
use strict
use warnings
my $i = 0;
while (0);
do {} until 0;
for (0..0) {};
for (1..4) { print 2*$_, "\n", foreach (1..20);

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
