Question 58

h = h + 2

The loop variable update statement in the code is represented by the expression "h = h + 2". This statement increments the variable h by 2 in each iteration of the loop, allowing the loop to progress towards its termination condition.

A) Put h to output

This option describes an action taken within the loop but does not pertain to updating the loop variable. It simply outputs the current value of h and does not affect the progression of the loop.

B) h < 30

This choice represents the loop's condition that determines whether the loop continues to execute. It is not the update statement; rather, it is a condition used to check if the loop should continue running.

C) Integer h - 2

This option is incorrect as it suggests a declaration or a calculation involving subtraction, which is not relevant to the update of the loop variable. There is no operation that decrements h in this context, making this choice irrelevant.

D) h = h + 2

This choice accurately represents the loop variable update statement. It shows how the variable h is modified in each iteration of the loop, ensuring that the loop eventually terminates when h reaches or exceeds 30.

Conclusion

The correct answer, "h = h + 2", is essential for the loop's progression, as it updates the loop variable h in each iteration. The other options either describe actions or conditions unrelated to the update statement, thereby confirming that D is the only option that fulfills the requirement of representing the loop variable update.
