cond dimension, or the columns, could be reversed
and the rows stored in ascending order:

</p>
<pre class="programlisting">
int data[] = { 3, 2, 1, 0,  7, 6, 5, 4, 11, 10, 9, 8 };
int *a = data + 3;
int s[] = { 4, -1 };
</pre>
<p>
</p>
<p>
Finally, both dimensions could be stored in descending order:

</p>
<pre class="programlisting">
int data[] = {11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0};
int *a = data + 11;
int s[] = { -4, -1 };
</pre>

All of the above arrays are
