Genau hier.

Code:

   case 'a' :  
       {  
       // Declaration of szChEntered OK. Local scope.  
       char szChEntered[] = "Character entered was: ";  
       cout << szChEntered << "a\n";  
       }  
       break;  
  
   case 'b' :  
       // Value of szChEntered undefined.  
       cout << szChEntered << "b\n";  
       break;  
  
   default:  
       // Value of szChEntered undefined.  
       cout << szChEntered << "neither a nor b\n";  
       break;  
   }

einmal klammer nach Case einmal keine..
welcher sinn steckt dahinter.

Code:

  case Dings:
     MachWas();
     break;
  case Dings:
     MachWas();
     {
         MachWasViel?();
         Vielezeilen
