$stuff is the element at position 2 in the array at position 1, for instance. Arrays of Hashes in Perl Finally, it's worth noting here that we can form arrays of other data structures just as easily using the same method. Here's an example of an array of hashes (that is, an array of references to hashes).

Perl provides numerous special variables, which have their predefined meaning. We have a special variable, which is written as $[. This special variable is a scalar containing the first index of all arrays. Because Perl arrays have zero-based indexing, $[ will almost always be 0. But if you set $[ to 1 then all your arrays will use on-based

Array notes. We can initialize 2D arrays with a single statement—all the memory is part of a single region. Here is a simple function (subroutine) for printing 2-dimensional (2D) arrays in Perl. Function [edit | edit source] sub print_2d { my @array_2d=@_; for(my $i = 0; $i <= $#array_2d; $i++){ for(my $j = 0; $j <= $#{$array_2d[$i]} ; $j++){ print "$array_2d[$i][$j] "; } print "\n"; } } Example [edit | edit source] Code: It is possible to have a 2D array in Perl that is irregular.

The way you create 2D arrays in Perl is to make a list of lists, that is, suppose you have, @matrix[$i][$j], the rows labelled $i contain pointers to other lists. You can think of this by considering a column of entries, and coming out perpendicular to these entries a separate list of values. 2002-12-25 Perl multidimensional arrays are arrays with more than one dimension.
