Easy Pointers

Solve in Playground →

Problem Statement

Write a C++ program that declares an array of integers and uses pointer arithmetic to traverse and print its elements.

Input Format

First line: N. Second line: N space-separated integers.

Output Format

Print array elements separated by a space using pointers.

Constraints

1 <= N <= 1000

Sample Input

4
10 20 30 40

Sample Output

10 20 30 40

Explanation

Pointer arithmetic allows navigating array elements by incrementing pointer addresses.

Starter Code

#include <iostream>
#include <vector>

int main() {
    int n;
    if (std::cin >> n) {
        std::vector<int> arr(n);
        for (int i = 0; i < n; i++) std::cin >> arr[i];
        int *ptr = arr.data();
        // Write your code here using ptr arithmetic
    }
    return 0;
}
