in thread alphabet counting

i have problem with hash printing !!!

You could guess that any such problems could be easily resolved... did you try something like this:

print "$k => $h{$k}\n" for my $k (sort keys %h);
?

    Hmm...

    my %h = ( a => 1, b => 2, c => 3 ); print "$k => $h{$k}\n" for my $k (sort keys %h);

    Output:

    syntax error at D:\progs\perl\junk.pl line 5, near "$k (" Execution of D:\progs\perl\junk.pl aborted due to compilation errors.

    Maybe you meant something like:

    print "$_ => $h{$_}\n" for sort keys %h;

    Or the (no doubt) more newbie-friendly:

    for my $k ( sort keys %h ) { print "$k => $h{$k}\n"; };

      ++ seven hours and several upvotes later. It's amazing how few people are trying around here these days.

      -sauoq
