Why a struct?

Why are the size and origin variables structs and not arrays? Would they ever need anything besides an int or maybe a float? Is there any benefit in using struct vs array if you know its only going to be one type?

I'm not sure of the exact reason, but I do know that in C arrays can not store two different datatype ( thats why they made structs which are similar in structure but can hold different data types). I would guess that the struct in question here is probably storing numbers but of different types, i.e. floats and ints.
