C

STEP: 1

#include <stdio.h>

int main() {
	int A[] = {8, 1, 3, 3, 8, 1, 1, 3, 8, 8};
	int n = sizeof(A) / sizeof(A[0]);
	for (int i = 0; i < n; i++) printf("%d\n", A[i]);
	return 0;
}

STEP: 2

#include <stdio.h>

const int N = 10;

int main() {
	int A[N];
	for (int i = 0; i < N; i++) scanf("%d", &A[i]);
	for (int i = 0; i < N; i++) printf("%d\n", A[i]);
	return 0;
}

STEP: 3

#include <stdio.h>

int main() {
	int n;
	scanf("%d", &n);
	int A[n];
	for (int i = 0; i < n; i++) scanf("%d", &A[i]);
	for (int i = 0; i < n; i++) printf("%d\n", A[i]);
	return 0;
}

}

STEP: 2

#include <iostream>
using namespace std;
