Switch statement outline

      switch( expression that evaluates to integer )
      { 
         case int_constant : statement(s);
         case int_constant : statement(s);
         case int_constant : statement(s);
         case int_constant : statement(s);

      }

   NOTE: the default part is optional but if used then default: is the 
         mandatory syntax.
