STL Container Pass-through delete element

STL container is the most error-prone to delete elements in the loop, the root cause is the iterator validity issue, where the generic Delete method is noted, which applies to all containers:

1 std::vector<int> myvec; 2 3 std::vector<int>::iterator it = myvec.begin (); 4  while (It! = myvec.end ()) 5 {6     it = myvec.erase (it); 7 }

The container list has a more alternative method of deletion, as shown in the following code:

std::list<int> mylist;std::list<int>::iterator it = mylist.begin ();  while (It! = Mylist.end ()) {    Mylist.erase (it+ +);}

However, it is not recommended to use this method to delete an element, because the method is not universal.
