Thread: Store some things in a float

This is how I've bashed at it, but I need help. I've never used sscanf() before that fact that my output is "0 - 0 - " kind of makes me think I'm doing something wrong (not necessarily with sscanf obviously).

Code:

int main(int argc, char *argv[])
{
        float   fCoords[3] = {0, 0, 0};
        char    *cInBuf = new char[60];

        std::cout << "] ";
        fgets (cInBuf, 60, stdin);

        sscanf (cInBuf, "%f %f %f", &fCoords[0], &fCoords[1], &fCoords[2]);
        for (int i = 0; i < 2; i++)
                std::cout << fCoords[i] << " - ";

        std::cout << std::endl;

        delete [] cInBuf;
        return 0;
}

EDIT: I give "/teleport 123 456 789" as the input.

Try:

Code:

        int num_read = sscanf (cInBuf, "%*/teleport %f %f %f", &fCoords[0], &fCoords[1], &fCoords[2]);
        if (num_read != 3)
        {
            std::cout << "Invalid format. Use: /teleport 123 456 789" << std::endl;
            std::cin.get();
            return 1;
         }

Or you could also use:

Code:

        int num_read = sscanf (cInBuf, "%*s %f %f %f", &fCoords[0], &fCoords[1], &fCoords[2]);
        if (num_read != 3)
        {
            std::cout << "Invalid format. Use: /teleport 123 456 789" << std::endl;
            std::cin.get();
            return 1;
         }

> for (int i = 0; i < 2; i++)
And I'm assuming you want 3 here:

Code:

        for (int i = 0; i < 3; i++)

Thanks for clearing that up, works now
