Compiler Error C2831

'operator operator' cannot have default parameters

Remarks

Only three operators can have default parameters:

• new

• Assignment =

• Left parenthesis (

Example

The following example generates C2831:

// C2831.cpp
// compile with: /c
#define BINOP <=
class A {
public:
   int i;
   int operator BINOP(int x = 1) {   // C2831
   // try the following line instead
   // int operator BINOP(int x) {
      return i+x;
   }
};
