You should have x start at 2 instead. You should not use floating point here at all, since you only need integer operations. General notes: Try to format your code better. Focus on using a consistent style. E.g. you have one else that starts immediately after a if brace (not even a space), and another with a newline in between. Don't use globals unless necessary. There is no reason for q to be global. Don't return without a value in a non-void (int) function. share|improve this answer edited Sep 1 '10 at 6:30 answered Sep 1 '10 at 6:23 Matthew Flaschen 175k28368450 5 Addition: You get a Floating point exception since your computer does not have a special case for integer division by 0. A better description would be Arithmetic exception, but this misnomer has a long history and probably cannot be changed anymore. –Roland Illig Oct 16 '10 at 13:32 add a comment| up vote 0 down vote It's caused by n % x where x = 0 in the first loop iteration. You can't calculate a modulus with respect to 0. share|improve t
