Re^2: Creating two dimensional array

I think you just answered a slightly different question. Most of us have interpreted the goal like this:

$VAR1 = [
          [
            'a',
            '1'
          ],
          [
            'b',
            '2'
          ],
          [
            'c',
            '3'
          ]
        ];

Your solution looks like this:

$VAR1 = [
          [
            'a',
            'b',
            'c'
          ],
          [
            '1',
            '2',
            '3'
          ]
        ];

Most of us have interpreted the goal like this Yes, I noticed. It would have been silly to post something that was already posted. There's no rule that says that the first dimension must be rows and the second must be columns. Here code that shows my solution does indeed use `@array1` as the first column and `@array2` as the second column. `my @array1 = qw( a b c ); my @array2 = qw( X Y Z ); my @matrix = (\@array1, \@array2); for my $row (0..$#{$matrix[0]}) { for my $col (0..$#matrix) { print $matrix[$col][$row], "\t"; } print "\n"; }` [download] `a X b Y c Z` [download] Update: Added code.

There's no rule that says that the first dimension must be rows and the second must be columns. True, but myself I tend to prefer the array of two-valued arrays structure myself. I think of the inner arrays as "points", i.e. pairs of (x,y) values, and typically you want to do things like push/pop points from your collection of data. But then it all depends on how the original poster is going to be graded -- I mean, on the details of the OP's application.	[reply]
