Question

Consider the following incomplete code segment, which is intended to print the sum of the digits in num. For example, when num is 12345, the code segment should print 15, which represents the sum 1 + 2 + 3 + 4 + 5.

int num = 12345;

int sum = 0;

/*  missing loop header */

{

sum += num % 10;

num /= 10;

}

System.out.println(sum);

Which of the following should replace /* missing loop header */ so that the code segment will work as intended?

A. while (num > 0)

B. while (num >= 0)

C. while (num > 1)

D. while (num > 2)

E. while (num > sum)

Answer 1

`Hey,

Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

while (num > 0)

SO, OPTION A IS CORRECT

Because at num=0 the loop should end since after it every time num will be 0

Kindly revert for any queries

Thanks.
