title: char \0 escape sequence - what does it mean?
body: <p>I'm reading this example</p>
  
  <p><a href="http://computer-graphics.se/hello-world-for-cuda.html" rel="noreferrer">The real "Hello World!" for CUDA!</a><br>
  What does the <code>\0</code> in </p>
  
  <pre><code>char str[16] = "Hello \0\0\0\0\0\0";
  </code></pre>
  
  <p>stand for?</p>
  
  <p>I'm not sure why the 16 char <code>str</code> has <code>"Hello "</code> inside it and then all zeroes then (this isn't a global variable). How can I be sure that it just contains zeroes?"</p>
