I'm using this function to generate a random number:
However I get an error message saying "not an allowed type", any ideas how to fix?Code:int flip (); int flip () { return 0;( (srand ( time (NULL) ) )%2); }
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...

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.
Hope is the first step on the road to disappointment.
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?Originally posted by crag2804

When all else fails, read the instructions.
If you're posting code, use code tags: [code] /* insert code here */ [/code]
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.
