Advanced Practice Question
Format: Iteration (for-loop count)
What is printed?
What is printed?
"apcs-keyword">int count = "apcs-number">0;
"apcs-keyword">for ("apcs-keyword">int i = "apcs-number">0; i < "apcs-number">10; i += "apcs-number">3)
{
count++;
}
System.out.println(count);
Difficulty: Hard |
Topic: Iteration (for-loop count) |
Cycle: 2 (Advanced)
Why This Answer?
`i` takes values 0, 3, 6, 9 (four iterations). Each iteration increments `count`, so it prints 4.
Common Mistake
Watch Out!
Stopping at `i = 6` and forgetting `i = 9` still satisfies `i < 10`.
AP Exam Strategy
List the actual `i` values the loop uses; don't guess.
