Question
For this exercise, the modulo operator is used to determine if the number is divisible by 10. Why does a 0
result mean that the number is divisible?
Answer
The modulo operator returns the remainder portion of a division operation. If one number is evenly divisible by another number, there will be no remainder. So, if the modulo operator returns a 0
, then it means that the number is evenly divisible by 10.
