This article is an instance of C + + dynamic binding (polymorphism) and gives a method of forcing the invocation of an object function (temporarily unbinding dynamic bindings)Note that until the runtime base class is specified to determine which

The exception security function (Exception-safe functions) does not leak resources or allow any data structures to corrupt even if an exception occurs. Such a function area is divided into three possible guarantees: basic type, strong type,
