Give the output of the following program segment: int n = 4279; int d; while(n > 0) { d = n % 10; System.out.println(d); n = n / 100; }

9 2

The trap is the divisor: the loop divides by 100, not 10, so it skips a digit each pass. Pass 1: n = 4279, d = 4279 % 10 = 9, prints 9, then n = 4279 / 100 = 42 Pass 2: n = 42, d = 42 % 10 = 2, prints 2, then n = 42 / 100 = 0 (integer division) Test: 0 > 0 is false, so the loop stops. Output is 9 and then 2. Anyone who reads /100 as /10 will answer 9, 7, 2, 4 — which is exactly what the question is checking. Always dry-run with the ACTUAL operators, not the familiar ones.
