Before explaining what a friend yuan is, Let's explain the disadvantages of the need for friends yuan and friends yuan: Generally, for common functions, it is impossible to protect members of the category class. To do so, all the members of the

Singleton mode is also called Singleton mode and Singleton mode. The Singleton mode ensures that a class has only one instance and provides a global access point for it. This instance is shared by all program modules. Such functional modules are

C ++ multi-Inheritance Multi-inheritance can be seen as an extension of single inheritance. Multi-inheritance means that a derived class has multiple base classes. The relationship between the derived class and each base class can still be

C ++ provides the following three types of compilation preprocessing functions: (1) macro definition (2) File Inclusion (3) Conditional compilation In C ++, we generally use const to define symbolic constants. Obviously, defining constants with
