[C++] Get Internal IP Address

[ZionHD]

It only works for Windows OS because it uses windows headers which are not included in linux os.
This code is to get the internal ip address of your pc using C++.

#pragma once

#include <iostream>
#include <string.h>

#include <WinSock2.h>
#define _WINSOCKAPI_
#include <ws2tcpip.h>

#include <windows.h>
#include <stdio.h>

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

using namespace std;

#define DEFAULT_VERSION 1.00

char *get_ip_addr();

int main()
{
    printf("~ IP Displayer %4.2f created by ZionHD ~\n", DEFAULT_VERSION);
    printf("~ Copyright (c) 2015 Console-Forums ~\n");
    printf("\n\n");

    WSAData wsaData;
    if (WSAStartup(MAKEWORD(1, 1), &wsaData) != 0) {
        printf("Failed at WSAStartup()\n");
        return 1;
    }

    char *ip = get_ip_addr();

    printf("IP Address: %s", ip);

    WSACleanup();
   
    return 0;
}

char *get_ip_addr()
{
    char ac[256];
    if (gethostname(ac, sizeof(ac)) == SOCKET_ERROR) {
        return "127.0.0.1";
    }

    struct hostent *phe = gethostbyname(ac);
    if (phe == 0) {
        return "127.0.0.1";
    }

    struct in_addr addr;
    memcpy(&addr, phe->h_addr_list[0], sizeof(struct in_addr));
    return inet_ntoa(addr);
}
