Consider the following program segment and select the output when n = 10: switch(n) { case 10: System.out.println(n * 2); case 4: System.out.println(n * 4); break; default: System.out.println(n); }

Answer
Exam answer
(a) 20 40.
Explanation
Control enters at case 10 and prints 10 * 2 = 20. There is NO break after that case, so execution falls through into case 4 and prints 10 * 4 = 40 — note it uses n, which is still 10, not the case label. The break at the end of case 4 then exits the switch, so default never runs. Output: 20 then 40, on separate lines because println is used.
In words
20 40.
