萌新求助(TCP聊天)
按教材上编了一个TCP聊天程序,但显示

    closesocket(socket_receive);
    closesocket(socket_server);
    WSACleanup();

}
客户端的代码:

    wVersionReuested=MAKEWORD(2,2);

    error=WSAStartup(wVersionReuested,&wsaData);
    if(error!=0)
    {
        printf("加载套接字失败!");
    }
    if(LOBYTE(wsaData.wVersion)!=2||HIBYTE(wsaData.wVersion)!=2)

    {

    Server_add.sin_family=AF_INET;

    if(bind(socket_server,(SOCKADDR*)&Server_add,sizeof(SOCKADDR))==SOCKET_ERROR)

    }

    if(listen(socket_server,5)<0)

    }

    socket_receive=accept(socket_server,(SOCKADDR*)&Client_add,&length);
    if(socket_receive==SOCKET_ERROR)
    {
        printf("连接失败\n");
    }

    while(1)
    {
        ReceiveLen=recv(socket_receive,Receivebuf,100,0);
        if(ReceiveLen<0)
        {
            printf("接收失败/n");
            printf("程序退出\n");
            break;
        }
        else
        {
            printf("client say:%s\n",Receivebuf);
        }
        printf("please enter the massage:");
        scanf("%s",Sendbuf);
        SendLen=send(socket_receive,Sendbuf,100,0);
        if(SendLen<0)
        {
            printf("发送失败\n");
        }
    }
    closesocket(socket_receive);
    closesocket(socket_server);
    WSACleanup();
    return 0;
}
有几个地方不知道该填什么地址,还有上面的几个错误。希望有大佬指点。

Server_add.sin_family = AF_INET;
    Server_add.sin_addr.S_un.S_addr = htonl("192.168.1.10");
    Server_add.sin_port = htons(5000);
    socket_server = socket(AF_INET, SOCK_STREAM, 0);
请问,这段代码里的主机ip应不应该这么填
