I don’t think he’s talking about the old effective C++ book, but rather the “effective modern C++” book as stated in the post.

Was printed in 2014. The older one which is `effective C++` is printed in 2005.
I thought it might be wasted money to get the old one but if its still worth it Ill definitely consider it!
