Designates the end of the reversed controlled sequence.

reverse_iterator rend();  

The member function returns a reverse iterator that points just beyond the beginning of the controlled sequence. Hence, it designates the end of the reverse sequence. You use it to obtain an iterator that designates the current end of the controlled sequence seen in reverse order, but its status can change if the length of the controlled sequence changes.
