class' : constructor syntax missing formal parameters

The constructor for the class does not specify any formal parameters. The declaration of a constructor must specify a formal parameter. (The list can be null.)

Add a pair of parentheses after class``::``class.

The following sample generates C2461:

// C2461.cpp  
// compile with: /c  
class C {  
   C::C;   // C2461  
   C::C();   // OK
