{
  CURL *curl;
  CURLcode res;

  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, \"http://www.google.com\");

Answer 1

This might not work right away but should give you an idea:

#include <string>
#include <curl.h>
#include <stdio.h>
size_t write_data(void *ptr, size_t size, size_t nmemb, FILE *stream) {
    size_t written;
    written = fwrite(ptr, size, nmemb, stream);
    return written;
}

int main() {
    std::string tempname = "temp";
    CURL *curl;
    CURLcode res;
    curl = curl_easy_init();
    if(curl) {
      FILE *fp = fopen(tempname.c_str(),"wb");
      curl_easy_setopt(curl, CURLOPT_URL, "http://www.google.com");
      curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data); 
      curl_easy_setopt(curl, CURLOPT_WRITEDATA, fp);
      res = curl_easy_perform(curl);
      curl_easy_cleanup(curl);
      fclose(fp);
      fp = fopen(tempname.c_str(),"rb");
      fseek (fp , 0 , SEEK_END);
      long lSize = ftell (fp);
      rewind(fp);
      char *buffer = new char[lSize+1];
      fread (buffer, 1, lSize, fp);
      buffer[lSize] = 0;
      fclose(fp);
      std::string content(buffer);
      delete [] buffer;
    }
}
