Summary of C ++ programming: use of virtual functionsFor a single class, whether the Destructor is a virtual function has no substantive significance. However, when the current class is used as the base class, whether the destructor of the base

Item 09-Never invoke virtual functions in constructors and destructors (never call virtual functions during construction or destruction)Why?Since the base class constructor executes earlier than the derived class constructor, the member variables of

The constructor can not be a virtual function, this is obviously, after all, virtual functions are corresponding to a virtual function table, virtual function table is the existence of object memory space, if the constructor is virtual, you need a

Today, we will introduce some basic knowledge about the C ++ virtual destructor in this article. I believe that beginners who have just been familiar with the C ++ programming language urgently need to explain the basic knowledge to increase their
