title: std::cout to print character N times
body: <p>How can I print a character N number of times using <code>std::cout</code> without looping?</p>
  
  <p>Is there a way to move the text cursor back to nullify the effect of <code>std::cout &lt;&lt; std::endl;</code>? i.e. to move up a line (say we never printed anything after doing the <code>std::cout &lt;&lt; std::endl;</code> operation).</p>
