Thread: how to scan a var in enum

Booleen is an enum type! There isn't room to hold a whole string like "vrai" in there! We went over this already. You need a temporary string to store the users input, then use strcmp like so:

Code:

typedef enum Booleen Booleen ;
enum Booleen {faux,vrai};

int main (void)
{
    Booleen b;
    char buf[50];

    scanf("%s", buf);
    if (strcmp(b, "vrai") == 0) {
        b = vrai;
    }
    else {
        b = faux;
    }
    printf("The value of b is %s\n", b == vrai ? "vrai" : "faux");

    return 0;
}

You have to translate the string the user types into the right enum value. scanf won't do it for you. You have to translate the enum value into a string to print. printf won't do it for you.

Also, notice those two blue lines. It's int main(void) and return an int at the end (usually zero). Read about why this is important here: Cprogramming.com FAQ > main() / void main() / int main() / int main(void) / int main(int argc, char *argv[]).

So I must use string ... ok

thank you very much
