switch statement with macros in C with visual studio 2010

Question

I'm trying to do something like this

#define GETCART1 0;
#define GETCART2 1;

void helper(int *Array,int length,int counter, int option){
    if (length > counter){
        switch(option){
        case (GETCART1) :

            break;
        }//switch
    }
}

and I get compile error when I replace GETCART1 with 0 its works fine. Why is that?

Drop the semicolons from the defines.

#define GETCART1 0;
                  ^ Drop this

If you don't, by the time the preprocessor is done, your code will end up looking like this:

switch(option){
case (0;) :
       ^
    break;
}

@Mr.32 This isn't compiler dependent. That's the whole point, it works **without the semicolons**. – cnicutar Dec 30 '11 at 07:57
