How C + + iterates over deleting elements inside Map/vector

New Skill get!ProblemFor containers inside C + +, we can use iterator for easy traversal. But when we make changes through iterator to Vector/map and so on, we need to be careful, because operations often lead to iterator failure, and subsequent behavior becomes unpredictable. Like what:#include The description of std::vector::erase in Cplusplus's reference is:

C + + prevents--map/set such as associative containers such as iterator invalidation in STL--vector/list/deque-How to prevent iterators from being invalidated-that is, the use of erase ()

Sequential containers::(vectors and lists and deque)The erase iterator not only invalidates all iterators that point to the deleted element, but also invalidates all iterators after the deleted element, so erase (iter++) cannot be used, but the return value of erase is the next valid iterator, so the correct method is:: For (iter = C.begin (); ITER! = C.end ();)iter = C.erase (ITER);Associative containers::(map and set are more commonly used) The eras
