Compiler Error C2835

user-defined conversion 'type' takes no formal parameters

User-defined type conversions cannot take formal parameters.

The following sample generates C2835:

// C2835.cpp
class A {
public:
   char v_char;

   A() { 
      v_char = 'A'; 
   };
   operator char(char a) {   // C2835
   // try the following line instead
   // operator char() {   
      return v_char + 1; 
   };
};

int main() {
   A a;
}
