**Given the following code, what is the final value of variable `i`?**

```c
int i;

for ( i = 0 ; i <= 4 ; i++ )
{
    printf("i is:\n", i);
}
```

*Answer in the box below:*  
[__________]

This code snippet is a simple `for` loop in C programming language. Here's a breakdown of what each part of the code does:

- `int i;`: This line declares an integer variable `i`.

- `for ( i = 0 ; i <= 4 ; i++ )`: This line initializes `i` to 0, sets the loop to continue executing as long as `i` is less than or equal to 4, and increments `i` by 1 after each iteration.

- `{ printf("i is:\n", i); }`: This block of code will be executed in each iteration. It prints the current value of `i` to the console.

- The loop starts with `i = 0` and continues until `i` exceeds 4. Therefore, the loop runs for `i` values 0, 1, 2, 3, and 4. After `i` is incremented from 4 to 5, the condition `i <= 4` becomes false, and the loop terminates.

Thus, the final value of `i` after the loop completes is 5.
