case selector of string

[Toasti]

Is it possible to make a switch with a string as it is in LabVIEW.

I want tor read a string from a File and then make my selection e.g.

string = "Laden"
switch (string)
{
case "Laden":
//do anything
break;
default:
break;

}

Ted,

According to the ANSI C/C++ standard, the switch statement can only take integers and single characters. In other words, switch will only work with int and char types, not with strings.

What of converting the strings to integers before doing the switch/case?

or what would be a good work around for something like the following?...

switch (atoi(myString)){

  case (atoi("myCase")):

    some code here;

    break;

  case (atoi("mySecondCase")):

    some code here;

    break;

}

Unfortunately your code cannot work: atoi converts the string representation of a number into its numerical equivalent. That is: atoi ("123") = 123; atoi ("myString") = 0!

In this environment the closer equivalent of a switch is a series of if:

if (!strcmp (myString, "myCase")) {

    some code here;

}

else if (!strcmp (myString, "mySecondCase")) {

    some code here;

}
