title: Const array in .hpp and .cpp file
body: <p>In my .hpp file I have </p>
  
  <pre><code>extern const double MY_CONST[44];
  </code></pre>
  
  <p>and in my .cpp file I have</p>
  
  <pre><code>const double MY_CONST[44];
  </code></pre>
  
  <p>and I get something like this: </p>
  
  <pre><code>error: uninitialized const 'MY_CONST' [-fpermissive]
  </code></pre>
  
  <p>Could you please tell me where the error is? Thanks</p>
