ABy default, the swap action is completed by the swap algorithm provided by the standard library:Namespace Std { templateThis function is at the heart of exception-safe programming and is a common mechanism for dealing with the possibility of self-assignment.However, for some types, these copying actions are not necessary: the basic one is "pointing to an object with a pointer, containing the real data"
