WebThe main drawback of lists and forward_lists compared to these other sequence containers is that they lack direct access to the elements by their position; For example, to access the sixth element in a list, one has to iterate from a known position (like the beginning or the end) to that position, which takes linear time in the distance between these. WebC++ Containers library std::list Returns a reverse iterator to the first element of the reversed list. It corresponds to the last element of the non-reversed list.
