OK, newbies! It's time for the first installment of the Brain Teaser. Click For some background on these "Brain Teasers". A reminder to all you Perl gurus out there, this is for newbies only! If you can come up with the answer without having to think very hard, please don't bother with this. If you learn something from this exercise, though, feel free to vote this node up.

The code below is designed to give you some practice with conditional statements. What do you predict will be output by this code? You can reveal the answer on the "replies" page. How this code works will be posted soon so be sure to bookmark this node.

#!/usr/bin/perl -w 1 use strict; 2 3 my @list = qw(1 2 3 4 5); 4 my $each = ""; 5 my $i = 0; 6 my @newlist = (); 7 8 foreach $each (@list) { 9 $each *= 2; 10 $newlist[$i] = $each; 11 ++$i; 12 } 13 14 for ($i= 0; $i<5; ++$i) { 15 print ($newlist[$i] - $list[$i], "\n"); 16 }

    [Your Mother]: Network, the 70's movie? Yes. Wonderful. Though it's been 20 years. Time to do it again.
    [Your Mother]: I miss the Sci-Fi authors of that era quite a lot...
    [LanX]: Network (1976 film) yeah
    [LanX]: yeah, we just had a discussion at work that SciFi in the 70s had more inovation
    [LanX]: (movies)
    [Your Mother]: Real ideas. Ideas grounded in reality as well.
    [LanX]: still some good newer ones. Oblivion had a great design, Moon was well acted
    [Your Mother]: Moon was mind bending and lovely and what's his nose Sam is *always* fun.
    [LanX]: the new BS Galactica series is my all time SoapFiction favourite ...
    [Your Mother]: I even liked "The Arrival" and I generally hate time travel (oriented) stuff.
