dump a string into array

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Maybe a very stupid question but I have this code:

my @words         = ( 'wordy', 'another' );
my $stemmed_words = Lingua::Stem::En::stem({ -words => \@words,
                                              -locale => 'en',
                                          -exceptions => \%exceptions,
                          });

print "$stemmed_words\n";
print Dumper( \$stemmed_words );
[download]

and it gives me this output:

ARRAY(0x4753160)
$VAR1 = \[
            'wordi',
            'anoth'
          ];
[download]

First of all I dont know why the $stemmed_words string output this "ARRAY(0x4753160)" and what if I want to store each value in an element of an array. Any suggestion is appreciated, In fact having a multi-dimensional array would be fine as well to store each word and it's stem in the same array.
Thanks in advance.

`$stemmed_words` is a reference to an array. Dereference it before using it, eg `$$stemmed_words[0]` or `$stemmed_words->[0]`: that index in the brackets works just like an array that isn't being dereferenced (`$foo[0]`), it's just the sigil or dereferencing arrow that's the difference. See perlreftut and maybe perldocdsc.	[reply] [d/l] [select]

Hi Anon, First of all `$stemmed_words` is an array reference to the word stems array derived from the module. Second `my @words_and_stems= (\@words , $stemmed_words);` [download] gives you both arrays in a single structure; `print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."`	[reply] [d/l] [select]

I think that you were looking for something like this: `#!/usr/bin/perl use strict; use warnings; use Data::Dumper::Concise; use Lingua::Stem::En; my $words = [ 'wordy', 'another' ]; my $stemmed_words = Lingua::Stem::En::stem({ -words => [$words], -locale => 'en', }); print Dumper($stemmed_words);` [download]	[reply] [d/l]

First of all your code is not working....and for your first question if $stemmed_words is an array reference than only it will give output as you have written	[reply]
