The answer is B. The program prints:
17 0
Why?
// divides and throws away the remainder: each friend gets 17 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 |
|---|---|
| 34 // 2 | 17 |
| 34 % 2 | 0 |
The code again
sweets = 34
friends = 2
print(sweets // friends, sweets % friends)Try it: change one number in the program and predict the new output before you run it.
