Am I correct to assume that there is no need to intialize a hash element to 0 or 1, when my purpose is just to increment it? I tried these two codes, and both of them seem to have produced the same result. Because of this I thought that if a hash element has no value and it is used on an arithmetic operation then its default value is zero. Am I correct? code1 
if(exists $myhash{$key})
{
 $myhash{$key} = $myhash{$key} + 1;
}
else
{
 $myhash{$key} = 1;
}

code2 
$myhash{$key} = $myhash{$key} + 1;
