You want to know how to write something to a file or what's the question?

#include <stdio.h>
#include <winsock2.h>
#include <stdlib.h>

int main()
{
WSADATA wsaData;
int iResult;

iResult = WSAStartup(MAKEWORD(2, 2), &wsaData);
if (iResult != 0) {
         printf("WSAStartup failed: %d\n", iResult);
return 1;
}
   struct sockaddr_in info;
   ZeroMemory(&info, sizeof(info));
info.sin_family = AF_INET;
info.sin_port = htons(80);
struct in_addr addr;
struct hostent *remoteHost;
remoteHost = gethostbyname("google.com");
printf("Official name: %s\n", remoteHost->h_name);
if (remoteHost->h_addrtype == AF_INET) {
          int i = 0;
while (remoteHost->h_addr_list[i] != 0) {
         addr.s_addr = *(u_long *) remoteHost->h_addr_list[i++];
          info.sin_addr.s_addr = addr.s_addr;
printf("IP Address #%d: %s\n", i, inet_ntoa(addr));
}
}
SOCKET s = INVALID_SOCKET;

s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
iResult = connect(s, (struct sockaddr*)&info, sizeof(info));

if (iResult == SOCKET_ERROR)
{
       printf("connect failed: %d\n", WSAGetLastError());
}
char mesaj1[] = "GET / HTTP/1.0\r\nHost: www.google.com\r\nUser-Agent: Browser rudimentar\r\n\r\n";

iResult = send(s, mesaj1, sizeof(mesaj1), 0);
if (iResult == SOCKET_ERROR) {
printf("send failed: %d\n", WSAGetLastError());
}
char receiveBuffer[128];
ZeroMemory(receiveBuffer, sizeof(receiveBuffer));
do
{
iResult = recv(s, receiveBuffer, 64, 0);
printf(receiveBuffer);

ZeroMemory(receiveBuffer, sizeof(receiveBuffer));
}
while (iResult > 0);


FILE *file; 
file = fopen("code.txt","a+"); 
fprintf(file,"%s",receiveBuffer); 
fclose(file);
getchar(); 
WSACleanup();
return 0;
}

The program show html page of google in CLI , create a file "code.txt", but this file is empty. Why?

You zero out the data you received in line 53 and you're surprised that your file is empty?
Besides, line 51 and 60 are wrong. Neither method works correctly if there are null bytes in your data and line 51 will also fail miserably if the data contains any formatting sequences (%d, %s, etc.)
