Subject: sorting a hash
Hi,
I have a reference to a hash of hashes, something like:
my $ref = { c => { name => 'a', age => 20, }, b => { name => 'e', age => 24, }, a => { name => 'z', age => 14, }, };
I want to sort the persons with the codes 'a', 'b', and 'c' by their name,
and print something like:
"a has the name z and has 14 years". ... then the next person in order...
foreach my $key (sort (keys %$ref)){
print "$key => $ref->{$key}{name} is $ref->{$key}{age}\n";
}Thank you.
Teddy
