undefined reference to `__imp_WSAStartup'

/*
关于WSAStartup方法和WSACleanup方法引用出错的解决:
	错误：
	编译的时候出现 
	undefined reference to `__imp_WSAStartup'
	undefined reference to `__imp_WSACleanup'
	在一般编译器中不会直接连接编译wsock动态库，需要手动添加库
	首先可以尝试代码中直接引入动态库，#pragam comment(lib,"ws2_32");
	如果不行再手动添加库
	在vc中，点项目(project-->project option)在makefile中输入-L"ws2_32" 
	在dvc C++中点击工具(Tool)-->编译选项（Compile Option)在编译命令框中输入-lwsokt32
