How to get the digits of a number without converting it to a string/ char array?

Question

How do I get what the digits of a number are in C++ without converting it to strings or character arrays?

Answer 1

Use a sequence of mod 10 and div 10 operations (whatever the syntax is in C++) to assign the digits one at a time to other variables.

In pseudocode

lsd = number mod 10
number = number div 10
next lsd = number mod 10
number = number div 10

etc...

painful! ... but no strings or character arrays.
