We were suppose to make a simple program that tells if a number is prime or not, but my program keeps on crashing, the windows xp error message keeps on popping up, and I don't know what's wrong, can someone help me? btw, I'm using Dev c++

i haven't tried to run your program, but my guess is that it's trying to do a modulus by 0. |

you got this code all wrong... the division check should start with 2 ( cuz remember - prime is divisible by 1 and itself). Though that would be wrong too since 2 itself is a prime number. And would screw up your loop if sqrt(num) <2 I remember posting a really efficient algorithm for finding prime numbers... You should search for that on forum, that might come in handy ![]() |

yeah, I did that when I fixed the code lol, I was brain dead or something, recently, I keep finding myself in situations that I shouldn't be in... for example, in my data management class, I was doing permutations, and I thought P(n, r) was n! / r!... I'm making sooo many simple :newbie: mistakes.... |
