AP CSA Unit 2 Day 18: Iteration For Loop Count

February 6, 2026

Unit 2, Selection & Iteration • Cycle 2

Day 18 Advanced Practice • Harder Difficulty

Focus: Loop Step Count Hard Iteration (for-loop count)

Advanced Practice Question

Format: Iteration (for-loop count)

What is printed?

int count = 0;
for (int i = 0; i < 5; i++) {
    count++;
}
System.out.println(count);

Difficulty: Hard | Topic: Iteration (for-loop count) | Cycle: 2 (Advanced)

Why This Answer?

`i` values are 1, 3, 5, 7, 9 (five iterations). So c is 5.

Common Mistake

Watch Out!

Including 11 or assuming `<= 10` means 10 is visited (it's not with step 2 from 1).

AP Exam Strategy

List the i-values for stepped loops; endpoints aren't always hit.

This Cycle 2 HARD question tests loop step count. Review Unit 2 concepts to build mastery of selection and iteration.

Cycle 2 questions prepare you for the hardest AP CSA exam questions.
