Virtual (virtual), virtual (virtual) Virtual) Virtual keywords are used to modify methods, properties, indexers, or event declarations, and allow them to be rewritten in a derived class. Read a piece of code: UsingSystem; Class {

Reader's attention: When reading this article, you must have an understanding of the object model in the inheritance, because some examples in this article do not give the class member variable, if you do not understand the inherited object model, it may be slow to think, you feel unsure of the following "inheritance." inherited polymorphic Polymorphism literally means "multiple states." In object-oriented languages, many different implementations of interfaces are polymorphic. The straightforw

Http://www.cnblogs.com/fly1988happy/archive/2012/09/25/2701237.html1. polymorphicIn object-oriented languages, many different implementations of interfaces are polymorphic. Polymorphism refers to an instance (object) of a child class with a pointer to the parent class, and then invokes the member function of the actual subclass through a pointer to the parent class .Polymorphism is a pointer to a parent class type that allows a pointer to a subclass type, which is implemented by a

I. Virtual destructor We know that in order to correctly call the object's destructor, a top-level class with a hierarchy is generally required to define its destructor as a virtual function. When deleting an abstract class pointer, you must use a virtual function to find the true destructor. For example:ClassBase{Public:Base (){}

SummaryVirtual base class1. A class can be used as either a virtual base class or a non-virtual base class in a class family.2. In a derived class object, a virtual base class with the same name only produces one virtual base class sub-object, while a non-virtual base class

Virtual architecture management includes the use of automation, monitoring, and management tools to ensure that the hardware and software platforms can run efficiently. Virtualization technology allows virtual machines to run on any suitable rack-mounted or blade traditional server hardware platform. In the traditional architecture, administrators can easily identify the email server and deploy the database

Introduction I have never written a conceptual article, because I think it is useless to write these conceptual things in detail in books, today, I want to write a piece of whimsy. I will discuss with you the virtual base classes, virtual functions, and pure virtual functions. It is easy to get confused when you look at the name. But it doesn't matter. You will u
