已经包括string.h了，在键入"gets("还有参数提示，为什么编译却错误呢？！

代码如下：



#include<iostream.h>

#include<Winsock2.h>

#include<string.h>



#pragma comment(lib,"wsock32.lib")



int main()   

{   

    //加载套接字   

    WORD wVersionRequested;   

    WSADATA wsaData;

    int err;   

	int todo;

	wVersionRequested=MAKEWORD(1,1); 

	

	

	err=WSAStartup(wVersionRequested,&wsaData);   

	if (err!=0)   

	{   

        return -1;   

	}   

	

		  if (LOBYTE(wsaData.wVersion)!=1||   

			  HIBYTE(wsaData.wVersion)!=1)   

		  {   

			  WSACleanup();   

			  return -1;   

		  }

		  //创建套接字   

		  SOCKET sockClient=socket(AF_INET,SOCK_STREAM,0);   

		  SOCKADDR_IN addrSrv;

		  cout <<"是否默认本地服务器？1/0      ?";

		  cin >>todo;

		  if (todo)

			  addrSrv.sin_addr.S_un.S_addr=inet_addr("127.0.0.1");

		  else{

			  cout <<"请输入服务器IPv4地址：\n";

			  char addr[16];

			  gets(addr);

			  addrSrv.sin_addr.S_un.S_addr=inet_addr(addr);

		  } 

		  addrSrv.sin_family=AF_INET;   

		  addrSrv.sin_port=htons(6000);   

		  

		  //向服务器发送请求   

		  if (connect(sockClient,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR)))

			  cout <<"连接失败！\n";

		  else

			  cout <<"连接成功！\n"; 

}
