Constant multidimensional arrays

One of those things that has always puzzled me is how multidimensional
arrays work in C.  I've always avoided this and embedded multidim
arrays inside of 1-dim arrays using explicit coordinate mapping.

int temp[0x10][0x20];

In the definition of `temp`, is there an array of pointers involved?

    K&R: "In C, a two-dimentional array is really a one-dimensional
    array, each of whose elements is an array.".

So my confusion is mostly about the difference between an array and a
pointer.  These are not the same!  See the sizeof() macro.

The confuses arrises because an array is automatically converted to a
pointer whenever it is used in a pointer context.
