The way that I understand an "array of arrays" and multidimensional
arrays in C is that they are basicly synonymous with one another.
So, in a sense, you would have to
"code this mutlidimensionally. eg arr[5][4].."

Or:    int *arr[23];

Which is an array of 23 pointers to int.
With this array of pointers you would have to take care of the memory
requirements dynamicly.
But even then you would access them like you would in a multidimensional
array.
Or something like :    *(*(arr + x)) = number;   during assignment, or

printf("%d", *(*(arr + x)) );   to access them.

I hope this was helpful.
