Divisiblity of 5 without using % and / operator

Question

how to check whether a number is divisible by 5 or not without using % and / operator. I want a quickest algorithm for this problem.

Answer 1

bool trythis(int number){
  Int start = number;
  Do{
    start = start - 5;
  } while (start > 5)

  If (start == 5 || start == 0) {
    Return true;
  } else return false;
}
