Program Output
1. The given program fragment initializes two integer variables: $s = 0$ and $k = 1$.
2. It then enters a \texttt{while} loop that continues as long as $k < 12$.
3. Inside the loop, the statement $s := s * s * s$ updates $s$ by cubing the current value of $s$.
4. Next, $k$ is incremented by $1$ in each iteration to ensure eventual loop termination.
5. Let's analyze the loop iterations:
- At the start, $s = 0$.
- On the first iteration: $s = 0 * 0 * 0 = 0$.
- Since $s$ remains $0$, cubing zero in subsequent iterations will keep $s = 0$.
6. After $k$ increments from $1$ to $11$, the loop stops when $k = 12$.
7. The final value of $s$ is $0$.
8. Therefore, the program will print $0$.
Final answer: $0$
