    switch string


    Is there any way to make a string switch in c++ to make my code look better instead of using if and else if for each case? Like in .net?

    For instance:

    string str = "test";
    switch(str) {
    	case "test":
    	case "test":

    No, since the switch may only be used with integral types, or a type convertible to an integral type. So even if it does compile, you would probably end up with a very wrong answer.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    If you have a lot of strings, you can write a functions that work for each possible string, then put them in a map with the string as the key and the function pointer as the value. This is the command pattern. Then, when you have your string you just execute myFunctionMap[str].
