What is required for an 'iterator' to move out of range according to the implemented checks?

  1. It moves beyond the top of the stack

  2. It points to a null value

  3. The container becomes empty

  4. The iterator's index becomes negative

The correct answer is: It moves beyond the top of the stack

An iterator typically moves through a container, such as a stack, by accessing elements one by one. It is possible for an iterator to move out of range, which means it is no longer pointing to any element in the container. In this case, the iterator has moved beyond the top of the stack, meaning it has reached a position that is beyond the total number of elements in the container. Options B, C, and D are incorrect because they do not necessarily cause an iterator to move out of range. A null value can exist in a container without affecting the iterator's position. An empty container can still contain a valid iterator as long as it has not moved beyond the top of the stack. Additionally, an iterator's index can become negative without necessarily moving out of range, depending on the container's implementation.
