Question

What is the output of the following code fragment? int i = 1; int sum = 0; while (i <= 11) { sum = sum + i; i++; } System.out.println("The value of sum is " + sum); The value of sum is 65. The value of sum is 66. The value of sum is 55. The value of sum is 56.

Answer 1

Answer:

The value of sum is 66

Explanation:

i = 1

sum = 0

while (i <= 11) {  

sum = sum + i;

i++;  

}

i = 1

• sum = sum + i
• sum = 0 + 1
• sum = 1

i = 2

• sum = sum + i

• sum = 1 + 2
• sum = 3

i = 3

• sum = sum + i

• sum = 3 + 3
• sum = 6

i = 4

• sum = sum + i

• sum = 6 + 4
• sum = 10

i = 5

• sum = sum + i

• sum = 10 + 5
• sum = 15

i = 6

• sum = sum + i

• sum = 15 + 6
• sum = 21

i = 7

• sum = sum + i

• sum = 21 + 7
• sum = 28

i = 8

• sum = sum + i

• sum = 28 + 8
• sum = 36

i = 9

• sum = sum + i

• sum = 36 + 9
• sum = 45

i = 10

• sum = sum + i

• sum = 45 + 10
• sum = 55

i = 11

• sum = sum + i

• sum = 55 + 11
• sum = 66

i = 12 --> does not comply with the condition "i < = 11", the while loop is over
