Perl, creating a hash of hashes.
- by Mike
Based on my current understanding of hashes in Perl, I would expect this code to print "hello world." It instead prints nothing.
%a=();
%b=();
$b{str} = "hello";
$a{1}=%b;
$b=();
$b{str} = "world";
$a{2}=%b;
print "$a{1}{str} $a{2}{str}";
I assume that a hash is just like an array, so why can't I make a hash contain another?
