title: call by reference with array
body: <p>What I want to do is something like this:</p>
  
  <pre><code>void dosth(bool&amp; a) {
    a[2] = false;
  }
  
  int main() {
    bool a[10];
  
    dosth(a);
  
    return 0;
  }
  </code></pre>
  
  <p>I want to call by reference, with an array as argument. How to realize this?</p>
  
  <p>Thx</p>
