Using an accompanying integer value that holds the number of items stored in the array is the most common and efficient way to work with partially-filled arrays. This allows you to easily keep track of the number of items stored in the array, even if it is not completely full. Using a separate class or parallel array adds unnecessary complexity, and an accumulator may not always be applicable or efficient.
