Day 11 Advanced Practice • Harder Difficulty
Focus: Nested Loop Count Hard Iteration (nested loop count)

Advanced Practice Question

Format: Iteration (nested loop count)

What is printed?
"apcs-keyword">int c = "apcs-number">0;

"apcs-keyword">for ("apcs-keyword">int i = "apcs-number">0; i < "apcs-number">3; i++)
{
    "apcs-keyword">for ("apcs-keyword">int j = "apcs-number">1; j <= "apcs-number">2; j++)
    {
        c++;
    }
}

System.out.println(c);
Difficulty: Hard  |  Topic: Iteration (nested loop count)  |  Cycle: 2 (Advanced)
Why This Answer?

Outer loop runs 3 times. Inner loop runs 2 times each outer iteration. Total increments = 3 × 2 = 6.

Common Mistake
Watch Out!

Multiplying the wrong bounds (like 3 × 3) or missing that inner loop is `<= 2` (two iterations).

AP Exam Strategy

Count inner iterations first, then multiply by outer iterations.
