title: How to repeat a char using printf?
body: <p>I'd like to do something like <code>printf("?", count, char)</code> to repeat a character <code>count</code> times.</p>
  
  <p>What is the right format-string to accomplish this?</p>
  
  <p>EDIT: Yes, it is obvious that I could call <code>printf()</code> in a loop, but that is just what I wanted to avoid.</p>
