/*
Creating a Twitter post using a C program involves interacting with the Twitter API. Twitter's API requires authentication using OAuth tokens.
Writing a complete C program for this task would be beyond the scope of a simple response, but I can give you an overview of the steps involved.

1. X **Create a Twitter Developer Account:**
   - Go to the [Twitter Developer portal](https://developer.twitter.com/en/apps) and create a developer account.
   - Create a new app to obtain API keys and access tokens.

*/
//2. **Install a C HTTP Library:**
//   - You'll need an HTTP library to make requests to the Twitter API. One option is `libcurl`. You can download it from [here](https://curl.se/download.html) and follow the installation instructions.

//3. **Include Necessary Headers:**
// ```c
   #include <stdio.h>
   #include <stdlib.h>
   #include <string.h>
   #include <curl/curl.h>

//4. **Define Twitter API Credentials:**
//   - Use the API keys and access tokens obtained from the Twitter Developer portal.
   #define CONSUMER_KEY "your_consumer_key"
   #define CONSUMER_SECRET "your_consumer_secret"
   #define ACCESS_TOKEN "your_access_token"
   #define ACCESS_TOKEN_SECRET "your_access_token_secret"

//5. **Create Tweet Function:**
   size_t WriteCallback(void *contents, size_t size, size_t nmemb, void *userp) {
       // Handle the response from the Twitter API
       return size * nmemb;
   }

   void postToTwitter(const char *tweet) {
       CURL *curl;
       CURLcode res;

       curl_global_init(CURL_GLOBAL_DEFAULT);
       curl = curl_easy_init();
       if(curl) {
           char url[256];
           sprintf(url, "https://api.twitter.com/2/tweets");
           
           struct curl_slist *headers = NULL;
           headers = curl_slist_append(headers, "Content-Type: application/json");
           headers = curl_slist_append(headers, "Authorization: Bearer your_bearer_token");
           curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
           
           curl_easy_setopt(curl, CURLOPT_URL, url);
           curl_easy_setopt(curl, CURLOPT_POST, 1L);
           curl_easy_setopt(curl, CURLOPT_POSTFIELDS, tweet);
           curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback);

           res = curl_easy_perform(curl);

           if(res != CURLE_OK)
               fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(res));

           curl_easy_cleanup(curl);
           curl_global_cleanup();
       }
   }

//6. **Make the POST Request:**
   int main(void) {
       const char *tweet = "{\"status\": \"Hello, Twitter!\"}";
       postToTwitter(tweet);
       return 0;
   }
