title: error C2514: 'BLOCK' : CLASS HAS NO CONSTRUCTOR
body: <p>I get the error <code>error C2514: 'BLOCK' : CLASS HAS NO CONSTRUCTOR</code>  with a simple class like this:</p>
  
  <p>BLOCK.h</p>
  
  <pre><code>#pragma once
  #include "helpful.h"
  
  class WORLD;
  
  class BLOCK
  {
      public:
          short int type;
  
          void Render();
  
          BLOCK();
          ~BLOCK(void);
  };
  </code></pre>
  
  <p>BLOCK.cpp</p>
  
  <pre><code>#include "BLOCK.h"
  #include "WORLD.h"
  
  BLOCK::BLOCK(void)
  {
  }
  void BLOCK::Render()
  {
  }
  BLOCK::~BLOCK(void)
  {
  }
  </code></pre>
  
  <p>But the <code>BLOCK</code> class is defined, no?</p>
