title: Can I initialize an array of array with all 0s?
body: <p>I have this:</p>
  
  <pre><code>uint8_t buf[X][Y];
  </code></pre>
  
  <p>I would like to initialize all elements to 0. Will this do the trick:</p>
  
  <pre><code>uint8_t buf[X][Y] = { 0 };
  </code></pre>
  
  <p>? i.e. will it initialize all <code>X*Y</code> elements to 0?</p>
