Through Rtti, it is possible to pass the base classpointer or referenceTo retrieve the actual type of the object it refers to. C + + provides RTTI by using the following two operators. (1) typeID: Returns the actual type of the object that the

All say C + + memory management is a big hole. It's actually true.C + + has destructors, and C + + performs two actions whenever an object expires1. Execute the destructor.2. Delete all data for objects and objects.A lot of people will ask, since

From the point of view of data structure, stacks and queues are also linear tables, the particularity of which is that the basic operation of stacks and queues is a subset of linear table operations, which are linear tables with restricted operation;
