Hi, I want to find out 10001st prime number of the site Projecteuler, and here is my programme

and I'm getting the answer as 104149. I thougth I've written my code correctly, but yet I'm getting wrong answer. Could anyone please tell me the reason of not having a right result? A small hint is enougth.

When you get prime(25) to return true, get a pencil and paper, and write 1 2 3 4 . . . 24 25. Then go through your method (a complicated bit of programming, there) and work out which numbers it will reject. You need to count the iterations of the loop carefully.

Then find out how the "Sieve of Eratosthenes" works. Far better way of working out prime numbers.

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
