I have come up with the code below so far but I cant get it to work.
use strict use warnings

Clearly this isn't your actual code, as these statements are missing semicolons and would generate a syntax error. Please post actual code in the future, as it avoids a whole mess of problems like this, and often helps you answer your own question!

my $i = 0; while (0); do {} until 0; for (0..0) {};

It looks like you've managed to post something that looks like code you've tried, which is a start, but I doubt you've tried very hard to make this work, as your loops all very clearly do nothing. If you really are very stuck on how to write any sort of a loop, your course notes probably contain examples, plus the plethora of Perl beginner's material out there contains plenty:

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!

This looks like homework, and there's nothing wrong with that per se, but I would strongly encourage you to read some of the links I've provided and try to work out the basics for yourself, or this exercise will be little more than a colossal waste of your time, and, hey, you're worth it!

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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.
