There is a mistake on page 188 of C++ All-in-One for Dummies, 4th Edition that is based on a supposed April Fool’s prank that was actually initiated on March 26, 2018 (see https://www.modernescpp.com/index.php/no-new-new) and spread throughout the Internet to sites such as: https://www.fluentcpp.com/2018/04/01/cpp-will-no-longer-have-pointers/. The problem with pranks, especially pranks that linger because the people who perpetuate them haven’t removed them, is that other people tend to believe them, as in this post: https://stackoverflow.com/questions/59820879/are-new-and-delete-getting-deprecated-in-c#. Later, much later, as in the note on the Fluent C++ site, people admit that it was a joke, but still leave the errant material in place.
After I had discovered that this information was a joke, I had meant to remove two sentences from the book, but somehow they stayed intact. The two sentences in question appear in the “Understanding the Changes in Pointers for C++ 20” section:
Readers who already know something about pointers need to be aware of the changes in pointers for C++ 20, which is why it appears first. The essential thing to remember as you move to C++ 20 (where
new is deprecated) and then to C++ 23 (where
new is removed) is that pointers are going to change.
If you find any other references in the book that state that
new is deprecated or removed, they too will be modified or eliminated during the next printing. I apologize for any problems that the error has caused, especially to readers who are new to C++, and have submitted an errata to the publisher so that the error is fixed during the next printing. If you have any questions at all about the book, please contact me at John@JohnMuellerBooks.com.

I’ve just released a new book, C++ All-in-One for Dummies, 4th Edition, and I’d love to give five people in the US a chance to read it for free (I can’t accept requests from other countries due to the amount of postage required to send a book to you). There’s only one catch. In exchange for the free book, I’d appreciate your review of it on Amazon.com. Your reviews are important because they give other people some idea of what the book is like outside of my opinion of it.
This new edition contains an amazing amount of changes from the 3rd Edition, many of which you requested. Of course, I started by updating everything, so you see the latest version of Code::Blocks used in this book. Working with Code::Blocks makes C++ coding a lot easier, but Code::Blocks tends not to hide the details or add any odd background code like some IDEs do. In addition to the updates, you can expect to see these changes:
- Instructions on how to use your mobile device to write C++ code.
- Updates on how to work with
- Using functional programming techniques.
- Employing new operators, such as the spaceship operator.
- Understanding modifications to the Standard Library.
This new edition of the book comes in at a whopping 912 pages, so there is no expectation that you’ll read it cover-to-cover. What I would appreciate is your honest viewpoint on the topics that appeal to you most. If you’d like to participate in this drawing, please contact me at John@JohnMuellerBooks.com by 8 March 2021 by email with a subject of “C++ Book Drawing”. I need your name and address. I’ll post the winners of the contest (sans email addresses) in a future blog post.
