The code initializes the variable sum to 0 and reads in integers until num equals -1. For each integer read in, it adds it to sum. Therefore, the output of this code will be the sum of all integers entered before -1. In this case, the integers are 18, 25, 61, 6. Adding these all together gives a sum of 110, which is answer choice C.
