title: system () in stdio or stdlib?
body: <p>I used the <code>system("pause")</code> with <code>stdio.h</code> and it worked without error. When I looked at the stdio functions, <code>system()</code> is in stdlib. How come it worked, and here is the code?</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  
  int main() {
      printf("Hello World\n" );
      system("pause");
      return 0;
  }
  </code></pre>
