The answer is B. The program prints:
18 0
This answer was checked by running the program for real.
Why?
// divides and throws away the remainder: each friend gets 18 sweets. % gives the remainder: 0 sweets left over.
Trace table
A trace table follows the program step by step. Here’s this one:
| sum | answer |
|---|---|
| 36 // 2 | 18 |
| 36 % 2 | 0 |
The code again
sweets = 36
friends = 2
print(sweets // friends, sweets % friends)Try it: change one number in the program and predict the new output before you run it.
