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

Reversed order digit extractor (eg. for 23 will be 3 and 2):

while (number > 0)
{
    int digit = number%10;
    number /= 10;
    //print digit
}

Normal order digit extractor (eg. for 23 will be 2 and 3):

std::stack sd;

while (number > 0)
{
    int digit = number%10;
    number /= 10;
    sd.push(digit);
}

while (!sd.empty())
{
    int digit = sd.top();
    sd.pop();
    //print digit
}
