Perl/Basics/Variables and Data Types/References/Hash

A hash reference is a scalar created using the \ operator as follows:

my %user; $user{'name'} = "hatter"; $user{'network'} = "irc.blackhatacademy.org";   my $hashref = \%user;

Once you've created a hashref (hash reference) you must use pointers to access a key:

print $user->{'name'} . "\n"; print $user->{'network'} . "\n";
