Simple way to download a file with cURL - c++

Question

In my program, I want to download a few files. So I took cURL and used this code (taken and modified a little bit from here Download file using libcurl in C/C++):
#include "curl.h"
using namespace std;
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 DlZip(){
CURL *curl;
FILE *fp;
CURLcode res;
string url = "http://wordpress.org/extend/plugins/about/readme.txt";
char outfilename[FILENAME_MAX] = "/Users/Me/Desktop/bbb.txt";
curl = curl_easy_init();
if (curl) {
fp = fopen(outfilename,"wb");
curl_easy_setopt(curl, CURLOPT_URL, url.c_str());
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);
}
return 0;
}
But nothing happened and there weren't any file on my desktop :-/
What is the problem with my code?
Or if you have a simple function to use, could you give me ?
Thanks!

Check Below code
#include <cstdio>
#include <curl/curl.h>
#include <curl/types.h>
#include <curl/easy.h>
#include <string>
using namespace std;
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(){
CURL *curl;
FILE *fp;
CURLcode res;
string url = "http://www.joes-hardware.com/tools.html";
char outfilename[FILENAME_MAX] = "./MyText.txt";
curl = curl_easy_init();
if (curl) {
fp = fopen(outfilename,"wb");
curl_easy_setopt(curl, CURLOPT_URL, url.c_str());
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);
}
return 0;
}
It works fine.
The problem is - this code is not able to use https and hence when the url provided by you when opened in browser and through above code - produce separate responses.
