  <p><strong>My Code:</strong></p>
  
  <pre class="lang-java prettyprint-override"><code>for (int i = 0, k = 0; i &lt; final_numbers.size(); i++) {
      for (int j = 0; j &lt; final_numbers[i].second.size(); j++) {
          char add_c[6];
          _itoa_s(final_numbers[i].second[j], add_c, 6, 16);
          qr_code_string.append(add_c);
          qr_code_string.append("-");
      }
  }
  </code></pre>
  
  <p>I am trying to run my c++ program on Android studio Native-NDK.
  But the compiler shows me this error. <strong>use of undeclared identifier '_itoa_s'</strong></p>
  
  <p>Does anybody have any solution?</p>
