What must be done to make sure the 'iterator' points to the last element in the container?

  1. Assign it the return value of 'end()'

  2. Set its index to 'ssize - 1'

  3. Manually iterate through the container to the last element

  4. Call the 'begin()' function and add the size of the container

The correct answer is: Assign it the return value of 'end()'

Assigning the 'iterator' the return value of 'end()' ensures it is pointing to the last element in the container. Option B only sets the index of the iterator, not the actual element. Option C is inefficient and should be avoided unless necessary. Option D may cause the iterator to go beyond the bounds of the container. Therefore, option A is the correct and most efficient way to ensure the iterator is pointing to the last element in the container.
