Vc to get the computer name and IP address method

This article illustrates how vc gets the computer name and IP address. Share with you for your reference. The specific implementation method is as follows:

#include <winsock2.h> 
#include <stdio.h> 
#pragma comment(lib,"ws2_32.lib")
void main() 
{ 
WSADATA wsadata; 
WORD dwVersionRequested; 
int err; 
err=WSAStartup(dwVersionRequested,&wsadata); 
char hostname[128]; 
if(gethostname(hostname,128)==0) 
{ 
  printf("%sn",hostname);//Computer name
} 
char buf[20];
//memset(buf,0,80);
struct hostent *pHost = gethostbyname(hostname);
for (int i = 0; pHost != NULL && pHost->h_addr_list[i] != NULL; i++) 
{  
  //Put it in a character array for easy application
  strcpy(buf,inet_ntoa(*(struct in_addr *)pHost->h_addr_list[i]));
  //inet_ntoa(*(struct in_addr *)pHost->h_addr_list[i]);
  //The IP address
  printf("%sn",buf);
} 
WSACleanup(); 
}

Hope that this article described the VC programming for you to help.
