title: What is sizeof(something) == 0?
body: <p>I have a template that takes a struct with different values, for example:</p>
  
  <pre><code>struct Something
  {
      char str[10];
      int value;
      ...
      ...
  };
  </code></pre>
  
  <p>And inside the function I use the sizeof operator: jump in memory <code>sizeof(Something);</code></p>
  
  <p>Sometimes I would like to not jump anything at all; I want sizeof to return zero. If I put in an empty struct it will return 1; what can I put in the template to make sizeof return zero?</p>
