If you do not know the size of the array needed, you can create an array large enough to hold any number of entries and tell users to enter a predetermined sentinel value after they enter the last value. Using this approach:
A) requires that you increment a counter as values are entered so that you know how many elements are stored in your array
B) is preferred to defining a static sized array.
C) requires that you dimension the array to hold at least 100 entries.
D) requires the array be defined to hold string elements.
