Re: C-Style Struct?

[Mr. Newb]

To BrowserUK, I ran your code, the output is just 'thing'. I would expect it to print 123. What does that line ( print $thing{ list }[123]) do?

[Anonymous Monk]

just like in c/c++, its the 124th element of that array

My self has few answers, that's why I come here. How would I iterate through the array $thing{list}? ie, what would I write for a foreach loop?

my %thing = ( name => 'fred', count => 100, list => [ 1..10 ] );

print $thing{ list }[ 3 ];
4

for my $item ( @{ $thing{ list } } ) {
    print $item;

for( my $index=0; $index < @{ $thing{ list } }; ++$index ) {
    print "$index : $thing{ list }[ $index ]";
