Problem Statement

Write a C++ program that traverses an array and prints its elements using pointer subscripts (`ptr[i]`).

Input Format

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

Output Format

Print array elements separated by a space.

Constraints

1 <= N <= 1000

Sample Input

3
100 200 300

Sample Output

100 200 300

Explanation

Demonstrates index subscripting notation on pointer variables.

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[i]
    }
    return 0;
}

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
