Explanation / Answer
(11)
(a) Initially variable count is initialized to 0.
(b) do-while loop iterates i from 0 to 11. When i value is 11 the loop gets stopped.
(c) So the given code prints 11 times.
Hence correct option is (A)

(12)
(a) Initially variables sum and item are initialized to 0
sum = 0, item = 0 => item = 1, sum = 1
sum = 1, item = 1 => item = 2, sum = 3
sum = 3, item = 2 => item = 3, sum = 6
When value of sum is 6, break statement gets executed and iteration gets stopped.
Hence correct option is (C)

(a) Initially i is set to 0.
(b) for loop gets iterated from 0 to 10. When the value of i is 10, condition i<10 evaluates to false and the loop iteration gets stopped.
(c) Value of i after executing the loop is 11.
Hence correct option is (B)

(14)
(a) Initially variable count is initialized to 0.
(b) while loop iterates i from 0 to 10. When i value is 10 the loop gets stopped.
(c) So the given code prints "Welcome to Java" statement 10 times.
Hence correct option is (D)

(15)
(a) Initially variable count is initialized to 0.
(b) while loop iterates i from 1 to 11. When i value is 11 the loop gets stopped.
(c) So the given code prints "Welcome to Java" statement 10 times.
Hence correct option is (B)
