2D array in perl script

Learning 2D array in perl script. Just wonder how to put array in 2D

Code:

#!/apps/perl/bin/perl

system(clear);
foreach $nn ( 0 .. 4)
{
        foreach $n (0 .. 9)
        {
                $array[$n][$nn] = $n ;
                print(" array is :$array[$n][$nn]\n");
        }
        #push(@array2, "\n");
}
print("\n\nFinal array2 is :\n @array\n");

what i got is
Final array2 is :
ARRAY(0xe76aed0) ARRAY(0xe76af00) ARRAY(0xe76af30) ARRAY(0xe76af60) ARRAY(0xe76af90) ARRAY(0xe76afc0) ARRAY(0xe76aff0) ARRAY(0xe76b020) ARRAY(0xe76b050) ARRAY(0xe76b080)

That looks a lot like C code. Could you please explain the problem you're trying to solve in Perl? (i.e. "This is the problem, and this is my goal.") As a general (personal) rule, if so much as the idea of two-dimensional arrays pops into my head, I probably need to rethink my approach.

the only programming i learn is C programming. (i am not in software, i need some simple perl script to ease off my work)

The problem is how to aassign multiple arrays & then read the multiple arrays.
My actual script is a bit complicated which need multiple arrays & the arrays is a variable depends on the inputs.

I suggest that you may wish to explore such questions at http://www.perlmonks.org.

Basically, the Perl language supplies only "one-dimensional" lists and arrays and hashes, but says that any of those elements could be "a reference to" anything-at-all. So, your "two-dimensional" (or "n"-dimensional) data structure is built up out of a list or array, in which each element consists of "a reference to" another such list or array, ad infinitum.
