DRAFT:

Overview This program demonstrates how to classify NASA exoplanets based on their characteristics using the NASA Exoplanet API. The program fetches data from the API and performs clustering using the K-Means algorithm to group exoplanets into different categories.

Requirements C++ compiler cURL library for making API requests JSON library for parsing API response

Installation Install cURL library: sudo apt-get install libcurl4-openssl-dev Install JSON library (e.g., nlohmann/json):

git clone https://github.com/nlohmann/json.git
cd json
mkdir build
cd build
cmake ..
make
sudo make install

Compile the program: g++ exoplanet_classification.cpp -o exoplanet_classification -lcurl

Usage

#include <iostream>
#include <curl/curl.h>
#include <nlohmann/json.hpp>

using json = nlohmann::json;

// Function to make API request
size_t write_callback(void* contents, size_t size, size_t nmemb, void* userp) {
    ((std::string*)userp)->append((char*)contents, size * nmemb);
    return size * nmemb;
}

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

    curl = curl_easy_init();
    if (curl) {
        curl_easy_setopt(curl, CURLOPT_URL, "https://exoplanetarchive.ipac.caltech.edu/cgi-bin/nstedAPI/nph-nstedAPI?table=exoplanets&format=json");
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_callback);
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, &response_str);
        res = curl_easy_perform(curl);
        curl_easy_cleanup(curl);
    }

    json response_json = json::parse(response_str);

    // Perform clustering algorithm (K-Means) on exoplanet data
    // ...

    return 0;
}
