Answer
(i) p = 1
2,3,3
Working
When p
is 1, case 1
is matched. a++
increments value of a
to 2. As there is no break
statement, fall through to case 2
happens. ++b
increments b
to 3. break
statement in case 2
transfers program control to println
statement and we get the output as 2,3,3.
(ii) p = 3
1,2,2
Working
When p
is 3, case 3
is matched. c--
decrements c
to 2. Program control moves to the println
statement and we get the output as 1,2,2.
