Thus, contiguous memory is allocated for three matrices a [0], a [1] and a [2].
WebC guarantees that when it allocates space for an array, a pointer to the first location after the end of the array is a valid pointer. That makes constructions such as this one valid, because the final value that start gets in the loop is end.
