zay yar, here is a hint for you.
A prime number is divisible only by 1 and by itself.
You have already used the modulo operator (%) in your code, and this is a good start.
To test the number p for primality, the simplest approach is to check each number higher than 1 and lower than p, if p is divisible by it.
You need to write a loop for this.
If any of the numbers are divisible, then p is not a prime.
(There are many possible optimization techniques to make this algorithm more efficient for larger numbers, but I am not going into that for now.)
