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";
};
