title: Unexplained C++ default int values
body: <p>I've been refactoring some code and I noticed some wonky behavior involving an uninitialized int array:</p>
  
  <pre><code>int arr[ARRAY_SIZE];
  </code></pre>
  
  <p>I set a break-point and it seems all values default to -858993460. Is there something special with this value? Any ideas why they don't default to 0?</p>
