title: Visual Studio C++ warning for no default constructor?
body: <p>Is there a warning in Visual Studio I can turn on for C++ to tell me when a class doesn't have a default constructor? The only ones I can find are <a href="https://msdn.microsoft.com/en-us/library/8dk81ahy.aspx" rel="nofollow noreferrer">C4623</a>, <a href="https://msdn.microsoft.com/en-us/library/2cf74y2b.aspx" rel="nofollow noreferrer">C4510</a> and <a href="https://msdn.microsoft.com/en-us/library/9zkz8dx6.aspx" rel="nofollow noreferrer">C2512</a> but they're for specific problems with the default constructor.</p>
  
  <p>I'm currently using VS2013.</p>
  
  <p>Update: I'm not saying there's anything wrong with not having a default constructor, I'm asking if there's an optional warning for it.</p>
