昨天我尝试用C ++创建一个套接字服务器,但是编译时出错了。 错误:

我的主要.cpp类:
// HabboV5.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
#include "Env.h"
using namespace std;
int _tmain(int argc, _TCHAR* argv[])

cout.write("hi", 2);
cout << "Hello World!" << endl;
Env::Network = new Network();
Env::Network->Start();

在链接器选项中(在项目上单击鼠标右键,链接器,输入),您需要将wsock32.lib
或ws2_32.lib
添加到输入文件列表中。
