I'd say you need to use strlen() or, since you know that size of each item in
the array, make another array that holds the size of each element, or make your
items[] array two-dimensional and hard code the sizes in there. Not very
elegant, but the compiler has no way of knowing what the sizes of the elements
are since you explicitly told it they were pointer items.
