A string array:
A) Stores an actual string in each of its elements.
B) Can only provide access to strings of a certain length.
C) Is actually an array of pointers.
D) Is always less memory efficient than an equivalent double-subscripted array.

Question

Quizplus · Accepted Answer

A string array is actually an array of pointers, where each pointer points to the memory location of a string. So, it does not store the actual string in each of its elements, but only a reference to the string stored elsewhere in memory.

Answer: D
 A string array is less memory efficient than an equivalent double-subscripted array because it requires additional memory to store the pointers to the strings. In addition, accessing elements in a string array requires an additional indirection to access the actual string data.
