enumerator 'identifier' in switch of enum 'enumeration' is not handled

The enumerate has no associated handler in a switch statement, and there is no default label.

This warning is off by default. See Compiler Warnings That Are Off by Default for more information.

The following sample generates C4062:

// C4062.cpp  
// compile with: /W4  
#pragma warning(default : 4062)  
enum E { a, b, c };  
void func ( E e ) {  
   switch(e) {  
      case a:  
      case b:  
      break;   // no default label  
   }   // C4062, enumerate 'c' not handled  
}  
  
int main() {  
}
