// Check that ranged function parameters are implemented correctly. These
// are pointers to an array of an arbitrary size. Their size is described as a
// range between two values. This is typically between 0 and a parameter such
// as NumItems. The range information helps the printing code print the entire
// range of the output rather than just the pointer or the first element.
