    That class of programs are called "Quines", for some reason which was unknown to me until I followed that link.

    There are some awesome ones on this site, like 3-D Stereogram, Self replicating source., quine madness, spiraling quine, and One-Line Quine for instance. Just type "Quine" in the search box, as I did, and you'll find plenty of examples.

    Note that if this is a homework assignment, I really don't recommend using solutions from here. Your teacher may already know about PerlMonks, and a lot of these solutions are pretty well known around here.

      And even if not, it is likely that the teacher will get suspicious at the proficiency of Perl skill most of these quines required to write.. (And he will likely be able to tell even without knowing Perl particularly well.)

      Mmmm, maybe they are learning about PerlMonks :)

    use Super Search with the term 'quine,' and you should run into a few nodes that can help.
