Step 1:Let's solve this step by step:
Step 2:: Understand the do-while loop structure
- A do-while loop always executes at least once before checking the condition - The loop body runs first, then the condition is evaluated - If the condition is true, the loop continues; if false, the loop stops
Step 3:: Analyze the initial condition
- The condition $$x > 100$$ is then checked
- Inside the loop, x is immediately set to 20
Step 4:: Evaluate the loop condition
- $$20 > 100$$ is $$false
- This means the loop will only execute ONE time - After the first iteration, the loop terminates because the condition is not met
Step 5:: Count loop executions
- The loop body runs exactly $$1$$ time
- The condition x > 100 is checked once - The loop then stops
Final Answer
Key Insights: - Do-while loops always execute at least once - The condition is checked AFTER the loop body runs - In this case, x is set to 20, which does not satisfy x > 100
