Compiler Error C2461

'class' : constructor syntax missing formal parameters

The constructor for the given class did not specify any formal parameters. The declaration of a constructor must specify a formal parameter list in parentheses. This list can be null.

Add a pair of parentheses after the class::class identifier.

The following is an example of this error:

class C
{
    C::C;        // error
    C::C();      // OK
};
