Need Help??

Your problem is that you're mixing up hashes (%hash) with hash references ({ key => value }) -- note the braces.

Replace the braces with parens and it should work:

my %hash = ('perl' => 1 , 'C' => 0) ;
[download]

This produces a flat list, not a hashref, which is exactly what assignment to a hash wants.

Alternatively you could use a hashref (= a scalar pointing to a hash) everywhere:

my $hash = {'perl' => 1 , 'C' => 0} ;
foreach my $key(sort keys %$hash)
{
     print "$key : $hash->{$key} \n" ;

        }
