Why is the 'end sentinel' iterator necessary?

To indicate the start of the container
To perform deletion operations
To indicate the end of the container bounds
To reserve extra memory

The correct answer is: To indicate the end of the container bounds

The 'end sentinel' iterator is necessary to indicate the end of the container bounds, which allows for proper looping and iteration over the container. Option A is incorrect because the 'end sentinel' iterator does not indicate the start of the container; rather, it marks the end. Option B is incorrect because the 'end sentinel' iterator is not used for deletion operations. Option D is incorrect because the 'end sentinel' iterator is not used to reserve extra memory; it is simply used to mark the end of the container. By indicating the end of the container bounds, the 'end sentinel' iterator allows for proper and efficient iteration over the container without going out of bounds.
