Displaying IPv4 address.

[MrCarlos132435]

Hello Cplusplus, first time poster here.

I've come with a question that will probably be a simple solution but it eludes me.

What I'd like to do is use inet_ntoa() to display my ip address to the screen. The code I have so far works great and was from: http://tangentsoft.net/wskfaq/examples/ipaddr.html

What I'd like is for this code to just display one ip address instead of iterating through the for(,,) statement.

Code:

// Borland C++ 5.0: bcc32.cpp getlocalip.cpp
// Visual C++ 5.0: cl getlocalip.cpp wsock32.lib
//
// This sample program is hereby placed in the public domain.

#include <iostream>
#include <winsock2.h>
#pragma comment (lib, "ws2_32.lib")
using namespace std;

int doit(int, char **)
{
    char ac[80];
    if (gethostname(ac, sizeof(ac)) == SOCKET_ERROR) {
        cerr << "Error " << WSAGetLastError() <<
                " when getting local host name." << endl;
        return 1;
    }
    cout << "Host name is " << ac << "." << endl;

    struct hostent *phe = gethostbyname(ac);
    if (phe == 0) {
        cerr << "Yow! Bad host lookup." << endl;
        return 1;
    }


//This part here:

    for (int i = 0; phe->h_addr_list[i] != 0; ++i) {
        struct in_addr addr;
        memcpy(&addr, phe->h_addr_list[i], sizeof(struct in_addr));
        cout << "Address " << i << ": " << inet_ntoa(addr) << endl;
    }
    
    return 0;
}

int main(int argc, char *argv[])
{
    WSAData wsaData;
    if (WSAStartup(MAKEWORD(1, 1), &wsaData) != 0) {
        return 255;
    }

    int retval = doit(argc, argv);

    WSACleanup();
	system("pause");

    return retval;
}

Thanks for any help :)
