    attaching more values to a case

    I know how to write a switch case, type in a char "a" and run case "a"

    But is it possible to somehow attach more than one value for what triggers the case?
    for instance, instead of case 'a': case a,b,c and make all three chars trigger the case?

    Yes, just allow follow-through by putting the relevant code followed by the break after the multiple cases.

    Got it, thanks. I thought there was a more efficient way than typing case after case .

    for instance

    instead of

    case 'a':
    case 'b':
    case 'b':

    print

    more like

    case 'a' 'b' 'c'

    print

    There is an extension on GCC:

    Code:
    switch (x) {
    // 'a', 'b', or 'c'...
    case 'a' ... 'c': dosomething(); break;
    }
    But this is not standard...
