This sounds like homework to me. On this group, we don't usually
answer homework questions directly, but help you to work the answer
out for yourself.

So, how far have you got already? What's not working?

Look up the Sieve of Eratosthenes.

Funny, I did the same just the other day. It's quite easy.

First of all, you can't start from zero, you have to start from one.

Just loop throught the numbers from one to the entered number. Store the
prime numbers in a list, and loop throught the list for each number
checking if any of them is evenly dividable by the number.
