what is the correct proceedure to check the number of elements in a

when extracting elements like
$hash->{$key}->[0],$hash->{$key}->[1],.etc is
there way to determine the number of elements [ ] in the
$hash->{$key} if is
not known so each element can be displayed.
Arrays in scalar context return the number of elements in the array.
Try this:
my $num_elements = @{ $hash->{$key };
