    I have question in int arr[n]; WHY THIS IS WORKING? I expect to be fail

    int main() {
    /* Enter your code here. Read input from STDIN. Print output to STDOUT */   
    int n;
    cin >> n;
    int arr[n];  //WHY THIS IS WORKING? 
    for (int i = 0; i < n; i ++) {
        cin >> arr[i];
    }
    
    for (int i = 0; i < n; i++) {
        cout << arr[n-1-i] << " ";
    }
    return 0;
}
