**Question:**  
What does the array `arr` contain after the following code segment is executed? Show the content of the entire array for full credit.

```csharp
int[] arr = new int[8];
arr[1] = 3;
arr[3] = 11;
arr[7] = 5;
int x = arr[1] + 1;
arr[x] = 44;
arr[arr[7]] = 7;
```

**Explanation:**  
- The code initializes an integer array `arr` with 8 elements, all initially set to 0.
- `arr[1] = 3;` sets the second element to 3.
- `arr[3] = 11;` sets the fourth element to 11.
- `arr[7] = 5;` sets the eighth element to 5.
- `int x = arr[1] + 1;` calculates `x` as `3 + 1`, which is 4. Therefore, `arr[x]` or `arr[4]` is set to 44.
- `arr[arr[7]] = 7;` uses the value at `arr[7]`, which is 5, to set `arr[5]` to 7.

**Final Array Content:**  
`arr = [0, 3, 0, 11, 44, 7, 0, 5]`
