c++ project wont connect to socket with error 10093 - c++

Question

Why can't this program connect to the socket?
I know that WSAStartup fails, but I can't figure out how to use it.

10093 is WSANOTINITIALISED, which means WSAStartup() has not been called yet. The documentation for WSAStartup is pretty clear, if a bit verbose, and even includes a fairly complete example.
You must call WSAStartup before using any other Winsock functions:
wVersionRequested = MAKEWORD(2, 2);
err = WSAStartup(wVersionRequested, &wsaData);
You may also want to checkout out the WinSock FAQ when learning to do WinSock programming.
