Question 357 of 481
1Z0-811 Control Flow and Loops Practice Question
A team is implementing a search algorithm that iterates over an array of integers. The loop should stop as soon as the target value is found. Which loop construct is most appropriate?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
For loop with break
The most appropriate loop construct for this scenario is a for loop with a break statement. A for loop provides a concise way to iterate over an array by index, and the break statement allows the loop to terminate immediately once the target value is found, avoiding unnecessary iterations. While a while loop with a flag variable could also work, the for loop is more idiomatic and less error-prone. An enhanced for loop supports break as well, but it lacks access to the loop index, which may be needed. A do-while loop is not suitable because it guarantees at least one iteration even if the array is empty or the target is found early. Therefore, option D is correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
While loop with a flag variable
Why it's wrong here
A while loop works but a for loop is more idiomatic for array iteration.
- ✗
Enhanced for loop with continue
Why it's wrong here
continue skips to next iteration, not suitable for early exit.
- ✗
Do-while loop
Why it's wrong here
Do-while always executes at least once, which may be redundant.
- ✓
For loop with break
Why this is correct
A for loop with break is the most direct way to iterate and stop on condition.
