The author here is either unfamiliar with the practice of C++ or being somewhat dishonest. These examples are all very non-idiomatic C++. I have not used Rust yet, but I am fairly certain that if I have a task in and I do it the wrong way in Rust and then do it the right way in C++, I am going to get junk from Rust and what I expected from C++. This article is not going to convince an experienced C++ programmer of anything, but to those that do not know C++ beware.
