title: Strange beep when using cout
body: <p>today when I was working on some code of mine I came across a beeping sound when printing a buffer to the screen.
  Here's the mysterious character that produces the beep: ''
  I don't know if you can see it, but my computer beeps when I try to print it like this: </p>
  
  <pre><code>cout&lt;&lt;(char)7&lt;&lt;endl;
  </code></pre>
  
  <p>Another point of interest is that the 'beep' doesn't originate from my on board beeper, but from my headphone/speaker </p>
  
  <p>Is this just my computer or there something wrong with the cout function?</p>
  
  <p>EDIT:</p>
  
  <p>But then why does printing this character produce the beep sound? does that mean that I could send other such characters through the cout function to produce different effects?</p>
