It first takes a variable named ‘n’ which holds the length of the array, later it runs ‘for loop’ respectively to take input of the array and to print the array by iterating through the loop.

 #include <iostream>
using namespace std;
 
 
int main() {
 
    int n;
    cin >> n;
    int arr[n];
 
    for(int i=0; i<n; i++){
        cin >> arr[i];
    }
 
    for(int j=n; j>0; j--){
        cout << arr[j-1] <<" ";
    }
    return 0;
}
