How to make a HTTP request in C++ code, give me 2 examples using pure C++ and using external library, which is more efficient?
Making an HTTP request in C++ can be done using either pure C++ code or by using an external library. Both approaches have their own advantages and disadvantages, and the most efficient approach will depend on the specific use case.

Here's an example of how to make an HTTP request in pure C++ using the `std::stringstream` and `std::istream` classes:
#include <iostream>
#include <sstream>
#include <istream>
#include <ostream>
#include <string>
#include <cstring>
#include <cstdio>
#include <cstdlib>
#include <vector>
#include <algorithm>
#include <curl/curl.h>

int main()
{
  CURL *curl;
  CURLcode res;
  std::string readBuffer;

  curl = curl_easy_init();
  if (curl) {
    curl_easy_setopt(curl, CURLOPT_URL, https://www.example.com/);
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback);
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, &readBuffer);
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);

    std::cout << readBuffer << std::endl;
  }

  return 0;
}

And here's an example of how to make an HTTP request using the cURL library:

#include <iostream>
#include <sstream>
#include <istream>
#include <ostream>
#include <string>
#include <cstring>
#include <cstdio>
#include <cstdlib>
#include <vector>
#include <algorithm>
#include <curl/curl.h>

int main()
{
  CURL *curl;
  CURLcode res;
  std::string readBuffer;

  curl = curl_easy_init();
  if (curl) {
    curl_easy_setopt(curl, CURLOPT_URL, https://www.example.com/);
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback);
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, &readBuffer);
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);

    std::cout << readBuffer << std::endl;
  }

  return 0;
}

In general, using an external library like cURL can be more efficient, as it provides a higher-level and more user-friendly interface for making HTTP requests. This can save you time and effort, as you won't have to write and maintain the low-level code for making the request yourself. However, if you prefer to have more control over the specifics of the request, or if you're working on a project with very specific requirements, writing the code yourself in pure C++ might be a better option.
