in thread Dereference array of arrays

Or even just:

use warnings; use strict; my $array_ref = [ [ '0.93', 'a1', 'b1' ], [ '0.89', 'a2', 'b2' ], [ '0.88', 'a3', 'b3' ], [ '0.87', 'a4', 'b4' ], [ '0.86', 'a5', 'b5' ] ]; for my $row (@$array_ref) { for my $element (@$row) { print $element, "\n"; # using say, or setting $\ locally would wo +rk as well } }
You often have no need to know the indexes when looping through an array. And since an array begins with index 0, you would skip the first element with : for ( 1 .. $#$val ) UPDATE: which is done on purpose, my bad \o/

    ..You often have no need to know the indexes when looping through an array. And since an array begins with index 0, you would skip the first element with : for ( 1 .. $#$val )..

    And how was I looping through the array of array provided by the OP? Please check Re: Dereference array of arrays again. OR maybe that is met for the OP.

    If you tell me, I'll forget.
    If you show me, I'll remember.
    if you involve me, I'll understand.
