Listing 2.8 is Listing 2.9 in the book

[philipjoep]

I have the Second Edition of C++ Concurrency (ISBN ending in 4693) and I'm very confused why this repo's numbering is different than the book and why the code doesn't match. For example, page 31-32 of the book has listing 2.9 shown, but the code is found in listing 2.8 in the repo. And then the code in the repo does not match the book. For example, at the end of the listing in the book, a standard for loop is used, whereas in the repo's listing, a std:for_each is used.

Why does the repo not match the book?
