A Tour of C++ (Third edition)
To focus on the book itself, the very first "hello world" example doesn't seem to work with any compiler. Literally<p><pre><code>  import std;

  int main()
  {
          std::cout << "Hello, World!\n";
  }

</code></pre>
I even tried futzing with the latest compilers - VS 2022 Preview and clang++ 16.0.0 and it wouldn't work. Perhaps it works in some specific earlier released versions? As somebody noted, perhaps this book is for reading and not for actually trying out the code. Very strange for a programming language book in 2022.
