I've updated the example to remove the extraneous const values. There’s no reason at all — In fact, it’s pretty much useless to do. I’ve updated the example to remove the extraneous const values.

When a function returns by value rather than reference, isn't the return value always constant? So why does it need to be declared as such in this case?

When the const is used at the end of a function, it means the entire function is const, and no member variables can be changed. When the const is used at the start of a function, it means the return type of the function is const. Neither the prefix nor postfix operator++ is const — however, the postfix one returns a const Digit.

You covered const member functions previously, where the const keyword is at the end of the statement in the function declaration; but I don't think you've covered what const does at the start of the statement here.

It's already written and on the site. I didn't include it as part of the main tutorial because it's not strictly related to C++, but it definitely is an important thing to know. I will add a note to the end of chapter 0 letting users know about the appendix, because I can see how it might be missed. Using the debugger is in the appendix, sections A.4 and A.5.

Thanks! Alex -

You can't return local values by reference (or address) without problems. Looking at the code examples, I don’t see where cResult is returned by reference. cResult is returned by value.
