One of the methods. Gives array of prime numbers

primeNumbers = Enumerable.Range(1, 10).Where(Function(n) (n > 1) AndAlso Enumerable.Range(2, n-1).Count(Function(m) n mod m = 0) = 1).ToArray

Hi @404_Error

Do this:

  1. Initialise num=2 & i=1
  2. Take a while & put condition num<=10
  3. Inside while, reset i=2
  4. Inside the while, add another while & set condition i<num.
  5. Inside this inner while, add if with condition - num mod i =0.
  6. If true, do num = num+1 & put break activity.
  7. If false, do i = i+1
  8. After inner while, add if condition.
  9. Condition for if - i = num. if true, write the number, as it is prime.
  10. In the end, do num = num+1 (near outer while ending)

Hope this helps,
Best Regards.
