Prerequisites Summary:A virtual function is associated with polymorphism, and polymorphism is associated with inheritance. So this article is on the inheritance level of the fuss. Without inheritance, nothing is to be talked about.virtual function Definition:A pointer to a base class, or a reference to a polymorphic class (subclass/derived Class) object that operates on it, calls its corresponding function according to a different class object, which

C++virtual function1. Definition: A member function declared as virtual in a base class and redefined in one or more derived classes [1]2.

Because both C + + and Java are object-oriented programming languages, their polymorphism is achieved by virtual functions and abstract functions, respectively.The virtual function of C + + can be overridden in subclasses, and the invocation is judged by the actual object, not by the pointer type (the invocation of the normal function is based on the current pointer type). A pure

The class file binary character stream is loaded into memory (method area) through the ClassLoader and virtual machines. After the layout and initialization of the memory, the virtual machine bytecode execution engine can execute the functions defined by the relevant code implementation program. The object that the virtual machine execution engine executes is a m

Introduction has never written a conceptual article, because I think that these conceptual things are written in the books and are very detailed and useless, and today I have a whim to write, Here is a discussion of the virtual base class, virtual functions and pure virtual functions, a look at the name of the people can easily feel confused.
