The answer is A. The program prints:
4 1
Why?
// divides and throws away the remainder: each friend gets 4 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 |
|---|---|
| 29 // 7 | 4 |
| 29 % 7 | 1 |
The code again
sweets = 29
friends = 7
print(sweets // friends, sweets % friends)Try it: change one number in the program and predict the new output before you run it.
