SOCKADDR_IN data type conversion

[user123]

Im using sockets, but I have a problem entering the IP adress.
I want to enter an IP adress by number.
gethostbyname("www.website.com") does not solve it, I need IP adress of a computer, not a website.
Problem is, the format I have to enter it is complicated.
I can't just use an int/float/whatever.
I found the "solution" here:
http://msdn.microsoft.com/en-us/library/aa922011.aspx
But I don't understand it. Not a single letter of it.
Struct within a struct with variables between or something?
I never used structs, only simple classes.
Is there an alternative to all this quantum mechanics?
How do I solve this?

 SOCKADDR_IN SockAddr;
SockAddr.sin_port = htons(80);
SockAddr.sin_family = AF_INET;

SockAddr.sin_addr.s_addr = // I want the IP adress here.. as simple as possible 

EDIT: applied solution, new error:

#include "Winsock2.h"
#include <iostream>
#include <sstream>
#include "Mstcpip.h"
#include "Ws2tcpip.h"
//#include <istream>
//using namespace std;

//#pragma comment(lib, "Ws2_32.lib")


std::string char2string(char[]);
int main()
{
	std::stringstream ss;
	std::cout << "Main called." << std::endl << "Enter IP adress..." << std::endl;
	char input[100];
	std::cin.getline(input, 12);
	//std::cout << char2string(input) << std::endl;
	SOCKADDR_IN SockAddr;
	SockAddr.sin_port = htons(80);
	SockAddr.sin_family = AF_INET;
	inet_pton(AF_INET, input, &(SockAddr.sin_addr));

	unsigned long adres = inet_addr(input);

	std::cout << "Ip adress: " << adres << std::endl;
	//system("pause");
	return 0;
}

4 errors, all saying unresolved externals, they dont mention any line of code, just the .exe and 3 obj files... help?

Error 1 error LNK2019: unresolved external symbol __imp__htons@4 referenced in function _main D:\vsprojects\chatapplication\chatapplication\main.obj chatapplication

You need inet_addr().

There's an example here.
