in reply to how to use two dimensional array?

You may find this syntax for convenient.

use strict; use warnings; my @array = ( [1,2], [7,5], [4,4], [2,2], [0,7], [3,4], [8,9], [3,6], [5,7], [7,2], ); foreach my $pair (@array) { my ($x, $y) = @$pair; print "$x $y \n"; }

    One of my favorite tidbits of the language - instead of your for loop:

    print "@$_\n" for @array;
      Very clever way of getting the same output, but I do not think it answers the original question. Also note your dependence om the default value of the special variable $LIST_SEPARATOR ($").
