# Programs of Loops

Find prime numbers and traverse arrays in a circular manner.

## We'll cover the following

## Store the first `n`

prime numbers in the array

The following program stores the first `n`

prime numbers to an array. The value of `n`

is chosen by the user, and any number can be used. Here’s how to solve this problem:

- Start with an empty array of
`n`

elements. - Store $2$ as the first prime number at the $0^{th}$ index.
- Keep checking every following integer by dividing it by every prime value in the array.
- Check $3$ by taking the remainder after dividing it by all the prime values in the array. The only value in the current array is $2$. Since the remainder is non-zero, $3$ is stored in the array.
- Then, check $4$ in the same way. Since the remainder of $4$ divided by $2$ is $0$, it’s not stored in the array.

Note:We have added a helper function`printArray`

to assist us in printing the array. We only need to pass the array and its size as arguments to the function and it will print the array.
