Erase () method of list in STL

Erase () the method is to delete the node specified by iterator, but note that iterator is also destroyed when the function is executed. In this case, the iterator operation will report an error. The following is about erase () correct use of methods

Method 1:

Std: list <> (itList = List. begin (); itList! = (WillDelete (* = ++

Method 2:

Std: list <> (itList = List. begin (); itList! = (WillDelete (* ++

Error Method 1:

Std: list <> (itList = List. begin (); itList! = List. end (); itList ++ (WillDelete (*

Error Method 2:

Std: list <> (itList = List. begin (); itList! = (WillDelete (* = List. erase (++

At the same time, it should be noted that std: list multithreading is not safe. Therefore, multithreading usually requires a lock on list operations to ensure security.
