Unsigned into range is 0-255 so, when i--; and the control reaches while (0>=0 ) conditions will remail true and after that it will again decrease value of zero and due to range it will rotate back to 255. So again 255>=0 ... And so on.. Loop will iterate infinite times.

Explanation:
Since i is an unsigned integer it can never become negative.
So the expression i-- >=0 will always be true, leading to an infinite loop.
