Reverse Array Using Pointer

Medium Pointer Fundamentals

Solve in Playground →

Problem Statement

Write a C program to reverse an array in-place using pointer manipulation.

Input Format

First line contains n. Second line contains n integers.

Output Format

Print the reversed array separated by spaces.

Constraints

1 <= n <= 100

Sample Input

5
1 2 3 4 5

Sample Output

5 4 3 2 1

Explanation

Use two pointers pointing to the start and end of the array, swapping values and moving pointers inward.

Starter Code

#include <stdio.h>

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        int arr[100];
        for (int i = 0; i < n; i++) {
            scanf("%d", &arr[i]);
        }
        // Write your code here to reverse array using pointers
    }
    return 0;
}
