title: Initialize empty array in class
body: <p>I've just tried:</p>
  
  <pre><code>class Test
  {
  
  public:
          int iArray[][];
  
  }
  </code></pre>
  
  <p>...is this not possible? Do I have to set a constant value?</p>
  
  <p>like:</p>
  
  <pre><code>class Test
  {
  public:
         const int iArray[5][4];
  }
  </code></pre>
  
  <p>I want to define [x][y] later, just have the placements there. Else it wouldn't be "dynamic" and I don't want to use a vector because I want to be able to access the values by "X" and "Y".</p>
