How I can move some element to the end of list. I s

Answer 1

A std::list is a doubly-linked list, which means you do not have random access to element n. You have to can remove the element, and then use push_back.

Answer 2

Use the list method splice()

void list::splice ( iterator position, list<T,Allocator>& x, iterator i );

Move iterator i from list x into current list at position "position"

Thus to move it to the end put

x.splice( x.end(), x, iter );

(they can both be the same list or different lists as long as the list from which the item is moved has the same type, both T and Allocator)

Answer 3

Remove it then append it to your list.
