Answer 2

Answer: The code prints the sum of array members 5,1,7 which equals 13.

Note: For correct output in for loop i-- should be equal to i++ else there will be a runtime error.

Explanation:

• a[0] = 5, a[1] = 1, a[2] = 7
• iteration will run for 3 times
• 1'st iteration sum = 0 + 5 = 5
• 2'nd time sum = 5 + 1 = 6
• 3'rd time sum = 6 + 7 = 13
• therefore in the end output = sum = 13
