while(my($key, $value) = each(%hash) ) { print "$key =>
$value\n"; }
my($key, $value); while(($key, $value) = each(%hash) ) {
print "$key => $value\n"; }
What is the different between these two code in case of "my"
usage ?

case 1:
by decalring "my" we are making the variable local.
So you cant access the value of those variable from the
outsite of that block.
case 2:
here you can access the value of the code from the
outside of that code.
"my" is generally used to protect the variable from
mingling.

my @array=('data1','data2'); my @array1=('data1','data2'); my ($i,$k); $i=7; $k=7; while($i){ $array [++$#array] = 'ree'; $i--; print "@array"; } while($k){ push(@array1,'ree'); $k--; print "@array1"; } Are these two while loop are doing the same functionality ? What may be the difference?
