The answer is D. The program prints:
3 1
Why?
// divides and throws away the remainder: each friend gets 3 sweets. % gives the remainder: 1 sweet left over.
Trace table
A trace table follows the program step by step. Here’s this one:
| sum | answer |
|---|---|
| 16 // 5 | 3 |
| 16 % 5 | 1 |
The code again
sweets = 16
friends = 5
print(sweets // friends, sweets % friends)Try it: change one number in the program and predict the new output before you run it.
