Recently I've been looking at C + + related projects, but it's always a blur to understand static member variables and static member functions in C + + classes, and I don't understand why static member variables are used in a class. So I collected

1. Destructors1. Destructors have no arguments and cannot be overloaded, so a class can have only one destructor. If the user does not have a definition, the compiler will generate it automatically. 2. static The local object is not destroyed at the

Recently see effective C + + often see some and static related content, hope that a comprehensive collation, if not all, also hope to add:Static member variables in Class 1Static members Unlike normal data members, static data members exist

In this regard, let me begin by saying something about:The callback function must be a static member function or a global function to implement a callback function, presumably because a normal C + + member function implies a function parameter, the

Summary of the use of C + + static member variables and static member functions:A. Static member variables:The declaration of a data member in the class body is preceded by the static keyword, which becomes a data member of that class. As with other

A static member function is a member function of a class that does not belong to any object of the class request, but is a function shared by all members of that class.For example, you have 10 people in your class (10 for Class one by one), and the

/*Classes that contain static data members do not allocate storage space for static data members when they are created, you can treat static data members as a global variable and encapsulate them in a class for two purposes(1) Restricting the scope

I. static member variables For all objects of a specific type, you may need to access a global variable. For example, count the number of created objects of a certain type.If we use global variables, the Data encapsulation will be broken. Generally,

Summary of the use of C + + static member variables and static member functions: one. Static member Variable:A data member in a class body is preceded by a static keyword, and the data member becomes a statically data member of the class. As with

A static member function is a member function of a class that does not belong to any of the objects requested by that class, but rather a function common to all members of that class. For example, there are 10 people in your class (10 for example,

Static member functionsAs with static data members, we can also create a static member function that serves the entire service of a class rather than the specific object of a class. Static member functions, like static data members, are internal
