Just a note - Data::Dump is not a core module, so the first step would be
to install it and then try Octavian's program.
You could also use the less pretty, but very functional, Data::Dumper
(which is a core module, so no extra installation is required):
use Data::Dumper;
my %hash = (a => 1, b => 2);
print Dumper \%hash;
Even more generally, if you want to work on everything in a hash, you can
iterate over its keys or key/value pairs using the 'keys' or 'each' keyword:
foreach my $key (keys %hash) {
print "$key => $hash{$key}\n";
}
while ( my ($key, $value) = each %hash ) {
print "$key => $value\n";
}
Hope this helps, T
