title: How to declare a fixed size for an array in C++
body: <p>Quick and stupid question.
  How do I declare the size for an array if I'm not allowed to use global variables?</p>
  
  <p>Suppose I have the file <code>Album.h</code>:</p>
  
  <pre><code>class Album {
  private:
      Song songs[MAX_SONGS];
  
      //...
  
  }
  </code></pre>
  
  <p>where do I put <code>MAX_SONGS = 30</code>? 
  <code>const int MAX_SONGS = 30</code>
  is considered a variable right?
  Please notice that the size should be known to the entire program.</p>
