DSA- Print extreme ends of an array

Given an array int arr[] = {10, 20, 30, 66, 5};

Output: 10 5 20 66 30

  
  int arr[] = {10, 20, 30, 50, 99, 5, 11, 13, 66,5};

  int start = 0;
  int arrLength = sizeof(arr) / sizeof(int);
  int end = arrLength - 1;

  while (start <= end) {
    if (start == end) {
      cout << arr[start] << " ";
    } else {
      cout << arr[start] << " ";
      cout << arr[end] << " ";
    }
    start++;
    end--;
  }
