[Solved] Filling arrays with prime numbers [closed]

Question

You set array[i] to i if i is a prime number. But you do not set array[i] to any value if i is not a prime number. You probably only want to store the prime numbers in array, so

void fillArray(int array[], const int N){
    for (int i = 2, j = 0; j < N; ++i){
        if (primenumber(i))
            array[j++] = i;
    }
}
