"Three". "3". "Threeeeeeeeeeeeeeeeee". "03". "003". "0003". "00000000000000003". "III". "٣". "11". "३". "三". "Γʹ".

What do all the above things have in common? They're all representations of the number three†. Are the representations different? Yes. Are the numbers they represent different? No. There is only one number three.

The number three is indistinguishable from the number three as there is only one number three. However, two representations of the number three may be distinct from each other, since they may use different symbols, or different rules for bringing the symbols together.

ints in C++ (and in pretty much every language with a similar data type) are used to handle *numbers*. So, if you assign the number three to a variable of such a type, you get the number three. You don't get any particular representation of it. It's the number three. You get a representation of it when you ask for one, like when you output it.

So, how do you tell the difference between "3" and "0003" if they represent the same number? Easy: you don't use numbers.

The fundamental problem here is that you think you are dealing with numbers, but aren't. You are concerned with the representations, not the numbers themselves. So you should use a data type that can handle representations instead of one that can handle numbers. I believe the simplest solution is to use std::string.
