Compiler Error C2533

'identifier' : constructors not allowed a return type

A constructor cannot have a return type (not even a void return type).

A common source of this error is a missing semicolon between the end of a class definition and the first constructor implementation. The compiler sees the class as a definition of the return type for the constructor function, and generates C2533.

The following sample generates C2533, and shows how to fix it:

// C2533.cpp  
// compile with: /c  
class X {  
public:  
   X();     
};  
  
int X::X() {}   // C2533 - constructor return type not allowed  
X::X() {}   // OK - fix by using no return type
