to get output of libcurl program

I'm new to libcurl and trying to get output of sample program codes, but no result.

Code:

#include <stdio.h>
#include <curl/curl.h>
 
int main(void)
{
  CURL *curl;
  CURLcode res;
 
  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "http://google.com");
    res = curl_easy_perform(curl);
 
    /* always cleanup */ 
    curl_easy_cleanup(curl);
  }
  return 0;
}

I'm using the following steps:
To compile: g++ sample.cpp -lcurl -o sample
To execute: ./sample
The program is compiled successsfully and after executing it returns to the promt again without showing any output.
Plz help.

You need to set up a writer. Look at curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, ....)
