synchronizing the service sideThe synchronization service side is also fairly straightforward. It requires two threads, one for receiving new clients, and the other for handling existing clients. It cannot use a single thread; A new client is a

In C + +, virtual functions can be very well implemented polymorphism, but there are certain limitations, this limitation is that the virtual function must be defined in the base class, even if it is an empty implementation.For example, the

The preceding two sections describe the Rvalue reference and its effect. The use of rvalue references is described below through the writing of a string class. With respect to c++98, the movement constructor and the move assignment operator are the

A template is a tool for implementing a code reuse mechanism that implements type parameterization, which defines a type as a parameter, enabling true code reusability.Template can be divided into two categories, one is a function template, the
