Switch Case statement:

1 Switch(expression)2 {3      Caseconstant-expression 1:4    {5 statement block 1;6        Break;7    }8 ...9     Caseconstant-expression N:Ten    { One statement block N; A        Break; -    } -     default: the    { -Statement Block n+1; -    } -}

When encountering multiple constants using the same statement block, I habitually use Pascal's notation, as in case 1..3,5, and the correct wording should be:

1  Case 1: Case 2: Case 3:2 {3      for(i=0; i<l3;i++) {4cout<<"X";5     }6      Break;7}

Feel a little trouble at this point, such as encountering case ' A '. Z ', instead of using if more convenient, from this point of view C + + case without Pascal convenience
