Re: Iterating over Arrays

Hello

Try with this code:

use strict;
use warnings;
use Data::Dumper;

my @words = ("this","that");

# With this code
$words[5] = "bad idea";

print Dumper \@words;

And it outputs:

$VAR1 = [
           'this',
           'that',
           undef,
           undef,
           undef,
           'bad idea'
         ];


so $words[2], $words[3], $words[4] have been defined as undef automatically.

You'd better use a "push" method for a list operation like this.

Thanks
