 | Graphical representation of a multidimensional C array e.g.
int ia[2][3][6];
[6] => Outermost index
[3] => Middle index
[2] => Innermost index
--------- --------- --------- --------- --------- ---------
| ia[0] | ia[1] | ia[2] | ia[3] | ia[4] | ia[5] |
--------- --------- --------- --------- --------- ---------
/ \ Outermost index [size 6]
/ \
/ \
---------------- ---------------- ----------------
| ia[0][0] | ia[0][1] | ia[0][2] |
---------------- ---------------- ----------------
/ \ Middle index [size 3]
/ \
/ \
---------------------- ----------------------
| ia[0][0][0] | ia[0][0][1] |
---------------------- ----------------------
Innermost index [size 2]

| The graphical representation of a multidimensional C array makes it
clear why only the "innermost" index may be unsized if the array is
initialized. In that case the value of the "unsized" index is the
number of entries that are specified in the initializer list.

| Another try (hopefully the format in this case will not be screwed up!)
int ia[2][3][6];
[6] => Outermost index
[3] => Middle index
[2] => Innermost index
* --------- --------- --------- --------- --------- ---------
* | ia[0] | ia[1] | ia[2] | ia[3] | ia[4] | ia[5] |
* --------- --------- --------- --------- --------- ---------
* / \ Outermost index [size 6]
* / \
* / \
* ---------------- ---------------- ----------------
* | ia[0][0] | ia[0][1] | ia[0][2] |
* ---------------- ---------------- ----------------
* / \ Middle index [size 3]
* / \
* / \
* ---------------------- ----------------------
* | ia[0][0][0] | ia[0][0][1] |
* ---------------------- ----------------------
* Innermost index [size 2]
