title: C - Format char array like printf
body: <p>I want to format a c string like <code>printf</code> does. For example:</p>
  
  <pre><code>char string[] = "Your Number:%i";
  int number = 33;
  // String should now be "Your Number:33"
  </code></pre>
  
  <p>Is there any library or a good way I could do this?</p>
