What does the operator[] return in the PStash class?

An integer
The size of the Stash
A pointer from the storage array
The total number of elements in the Stash

The correct answer is: A pointer from the storage array

The operator[] in the PStash class returns a pointer from the storage array. This is because the PStash class is a dynamic array data structure that stores objects in a continuous block of memory. Therefore, the operator[] is used to access elements in the array by their index, and it returns a pointer to the specified element. Option A is incorrect because the operator[] does not return an integer, it returns a pointer. Option B is incorrect because it returns the size of the Stash, not a pointer to an element. Option D is incorrect because it returns the total number of elements in the Stash, not a pointer to an element in the array.
