Hi isha,

If you want to manipulate the simple hash, then your hash will be like this,

my %myhash = ( 1 => 'a', 2=> 'b', 3=> 'a', 4=>'c');

To manipulate this simple hash, you can do like

use strict; my %myhash = ( 1 => 'a', 2=> 'b', 3=> 'a', 4=>'c'); for my $key (keys %myhash){ if($myhash{$key} eq 'a'){ print "KEY:$key\n"; } }

But you created the hash as

my %myhash = { 1 => 'a', 2=> 'b', 3=> 'a', 4=>'c'};

which is anonymous hash reference. To manipulate this hash reference, then you can do like

use strict; my $myhash = { 1 => 'a', 2=> 'b', 3=> 'a', 4=>'c'}; for my $key (keys %{$myhash}){ if(${$myhash}{$key} eq 'a'){ print "KEY:$key\n"; } }
