Hello
I have a problem with this code. I'm trying to connect to local dns server in order to get the ip of the hostname( that user would enter). For now, i'm just trying to connect to the local dns server, and this code gives me following 8 errors..
client.obj : error LNK2001: unresolved external symbol __imp__closesocket@4
client.obj : error LNK2001: unresolved external symbol __imp__connect@12
client.obj : error LNK2001: unresolved external symbol __imp__htons@4

return;
}

WSACleanup();
return;
}
char *ip= "208.67.222.222";
cout<<ip;

server.sin_family= AF_INET;
server.sin_addr.s_addr= inet_addr(ip);
server.sin_port= htons(53);
if(connect(client, (SOCKADDR*) &server, sizeof(server)) == SOCKET_ERROR)
{
cout<<"Connection cannot be established. \n";
WSACleanup();
return;
}
closesocket(client);
WSACleanup();
