Seeded rand problem

I'm using this function to generate a random number:

Code:

---

int flip ();
int flip () {
        return 0;( (srand ( time (NULL) ) )%2);
  }

---

However I get an error message saying "not an allowed type", any ideas how to fix?

I have included time.h by the way.

Thanks

Call srand once to seed the random number generator...then call rand() to generate the random numbers

The FAQ has a chapter on this...

http://www.cprogramming.com/boardfaq.html#random

You realize that this line only returns zero and nothing else ever is executed:

return 0;( (srand ( time (NULL) ) )%2);

You knew that, right?

Quzah.

Yeah, that was only in there while I was attempting to fix my problem. I often throw code around trying to see whats broken, it made sense at the time.

So... are you sorted now or not?

Yes thanks, I read the tutorials on the site to begin with but it didn't make it clear that you had to seed the rand () seperatly. Needless its sorted now, thanks all.
