c++ - 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

Given the number 12345 :

5 is 12345 % 10
4 is 12345 / 10 % 10
3 is 12345 / 100 % 10
2 is 12345 / 1000 % 10
1 is 12345 / 10000 % 10

I won't provide a complete code as this surely looks like homework, but I'm sure you get the pattern.
