in reply to Re: Square the array values.
in thread Square the array values.

Is this you are expecting.
use strict; use warnings; use Data::Dumper; my @array=(1,2,3); print Dumper \@array; my $len=$#array; while($len>=0) { $array[$len]=$array[$len]*$array[$len]; $len--; } print Dumper \@array;


Or use the following way.
my @array=(1,2,3); foreach (@array) { $_=$_*$_; }

    The latter is much better, though you could multiply and assign in place with =*:

    for (@array) { $_ *= $_; }

    ... or even use postfix iteration:

    $_ *= $_ for @array;
