In my most recent postings, I was dealing with first HoA and now HoH.
In my previous example code, I ended up with an output that looked
something like this:
jelly -- strawberry apple grape pear
jam -- strawberry apple grape
milk -- plain strawberry chocolate
I thought I'd prefer to have it listed more like this:
jelly -- strawberry
apple
grape
pear
jam -- strawberry
apple
grape
milk -- plain
strawberry
chocolate
So in the following snippet, I tried to add a "\n" onto the value of the
HoH.
for my $i ( keys %HoH ) {
%{$HoH{$i}} = join ("\n", %{$HoH{$i}}, "");
print "$i -- @{[ keys %{$HoH{$i}} ]}\n";
}
But now for an output, what I get is:
jelly -- strawberry
apple
grape
pear
jam -- strawberry
apple
grape
milk -- plain
strawberry
chocolate
This begs two questions:
1) am I correctly accessing the value of the HoH ?
2) where is the 'extra' "\n" coming from
Thanks,
Mike
