title: fprintf - Print a specific numbers of characters per line
body: <p>For example I have some x,y coordinate.
  How can I print multiple x,y on the screen so that I have only 4 of these coordinates per line.</p>
  
  <p>So let us say that all x and y are the same throughout and I want this printed out where x = 1 and y = 2.</p>
  
  <pre><code>1 2 1 2 1 2 1 2
  1 2 1 2 1 2 1 2
  1 2 1 2 1 2 1 2
  ..............
  </code></pre>
