In order to get the next element in the list one just needs to increase the iterator. However from any element in the list, is there a way to get directly to the head of a list? For example if iterator is pointing to the third element of a list, is there a way to get to the front of the list besides iterating backwards ?
Thanks
No, because
std::listis designed to model a doubly-linked list (and is usually implemented as one), and in a doubly linked list, each element only has pointers to the previous and next element in the list.
