The answer is C. The program prints:
6 1
This answer was checked by running the program for real.
Why?
// divides and throws away the remainder: each friend gets 6 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 |
|---|---|
| 19 // 3 | 6 |
| 19 % 3 | 1 |
The code again
sweets = 19
friends = 3
print(sweets // friends, sweets % friends)Try it: change one number in the program and predict the new output before you run it.
