Re: Hash from package

This is my first post -- I hope it helps! Looking at your code, modify it as follows: print("I have an Engine " . %{$car}->{'Engine'} . "\n"); print("I have " . %{$car}->{'Doors'} . " Doors\n"); print("The color is Colour " . %{$car}->{'Colour'} . "\n"); Don't forget the spaces as needed in the print command. Good Luck, Sagacity

Erm, `%{$hashref}->{'key'}` has some extra line noise in it. You'd really want either `$car->{'key'}`, or alternately `${ $car }{ 'key' }`. You don't use the hash sigil when accessing a single element, just like you don't use `@array[$idx]` to access a single element from an array.</nit>	[reply] [d/l] [select]

thanks for the post mate. however thats not quite what im after. that's cheating what you've suggested. i want those words you added in to come from the hash, not from adding to the print statement. ie. %hash => (Engine, 1800cc, Doors, 4, Color, blue) print %hash output is: Engine 1800cc Doors 4 Color blue do you see where im coming from?

I wouldn't call it cheating. You've already hardcoded some text and the hash key. Sagacity's suggestion is perfectly reasonable. You're probably asking the wrong question. "How do I get key values from a hash?" is more likely what you're after. `foreach my $key (keys %$car) { print "$key = $car->{$key}\n"; }` [download] --- my name's not Keith, and I'm not reasonable.
