switch expression not integral

The switch expression evaluates to a noninteger value. To resolve the error, use only integral values in switch statements.

The following sample generates C2050:

// C2050.cpp  
int main() {  
   int a = 1;  
   switch ("a") {   // C2050  
      case 1:  
         a = 0;  
      default:  
         a = 2;  
   }  
}  

Possible resolution:

// C2050b.cpp  
int main() {  
   int a = 1;  
   switch (a) {  
      case 1:  
         a = 0;  
      default:  
         a = 2;  
   }  
}
