Question

Quizplus · Accepted Answer

A partially filled array is used when the number of values to be stored is not fixed and can change at runtime. Therefore, an accompanying integer value that keeps track of the number of items stored in the array is used to determine the size of the partially filled array. This is why option D is the best choice.
