AP CSA Unit 2 Day 24: Iteration Nested Loop Count

February 6, 2026

Unit 2, Selection & Iteration • Cycle 2

Day 24 Advanced Practice • Harder Difficulty

Focus: Nested Loop Multiplication Hard Iteration (nested loop count)

Advanced Practice Question

Format: Iteration (nested loop count)

What is printed?

int count = 0;
for (int i = 0; i < 3; i++) {
    for (int j = 0; j < 4; j++) {
        count++;
    }
}
System.out.println(count);

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

Why This Answer?

Outer loop runs 2 times, inner loop runs 3 times each → 2 × 3 = 6.

Common Mistake

Watch Out!

Adding instead of multiplying the loop counts.

AP Exam Strategy

Nested loops multiply: outer iterations × inner iterations.

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