How do I split an int into its digits?

Question

How can I split an int in c++ to its single numbers? For example, I\'d like to split 23 to 2 and 3.

Answer 1

The following will do the trick

void splitNumber(std::list& digits, int number) {
  if (0 == number) { 
    digits.push_back(0);
  } else {
    while (number != 0) {
      int last = number % 10;
      digits.push_front(last);
      number = (number - last) / 10;
    }
  }
}
