Quizplus · Accepted Answer

The input values are 18 25 61 6 -1. The code reads in each value until it reaches -1. For each value that is not -1, it adds it to the variable sum and increments the variable num. So at the end, sum will equal 110 (18+25+61+6) and num will equal 4 (the number of values that were not -1). Therefore, the output will be 110/4 which is approximately equal to 27.5 which, after rounding, is equal to 28. So the output will be 28. Hence, the correct choice is C.
