写一段使用WinSock网络编程接口规范及VC++编程语言，基于TCP协议的流式套接字，采用多线程、客户/服务器模式，完成一个控制台的 “石头、剪刀、布” 人机对战游戏程序，其中服务器端代表机器选手

很高兴能够为您提供这个问题的解答。以下是基于TCP协议的流式套接字，采用多线程、客户/服务器模式，完成一个控制台的 “石头、剪刀、布” 人机对战游戏程序的示例代码：

服务器端：

    if (result != NO_ERROR) {
        cerr << "WSAStartup failed: " << result << endl;
        return 1;
    }

    // 创建 socket
    SOCKET serverSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

        }

在 Visual Studio 中，您可以使用 Visual C++ 集成开发环境来编译和运行这个程序。在运行之前，您需要在项目属性中添加 `ws2_32.lib` 作为附加依赖项。如果您使用的是其他编译器或开发环境，请相应地进行配置。
