Here's an oldie but goody.

Consider the following code:

#!/usr/bin/perl -w ################################ use strict; my $str="ABC"; $str++; printf "%s\n",$str; exit(0); [download]

The questions are:

1. Is this legal Perl?
2. What will be the output

The answers are:

1. Yes.
2. The output will be:

   --$ ./perl_question.pl ABD --$ [download]

You might be surprised by some of the answers you'll get.
