Review: The book itself I really like. The low rating is due to recieving the book in a very poor state. It came with the cover dirty, damaged and a lot of bent pages. I would return it, but I don't want to waste a good book.
Review: I think this book delivers on all of the promises on the back cover. Even as someone who primarily uses C++ every day, this book helped me sharpen my C skills and rediscover a simpler world where more time and attention can go to the problem at hand than lost to idiosyncrasies of C++. If you want to step into the world of high performance programming and don't want to dedicate years of your life (and significant real estate in your brain) to mastering C++, then this book is for you.

### ⭐⭐⭐⭐⭐ Review
*by T***Y on 11 April 2022*

This is the best reference I've read on using C in the modern day and taking advantage of C's latest features. It's also one of the best books on C that I've read. Highlights: It does a great job demonstrating implementing OOP concepts in C. A solid chapter on concurrency. Tips for needing to malloc/free memory less, and a better approach when needed. The Better Structures and Object-Oriented Programming in C were the stand-out chapters in the book. When the book was written, MSVC wasn't supporting C11. That has changed recently, which means the concepts in this book work whether you're using a POSIX toolchain or Microsoft Visual Studio. If you don't already know C, I don't think this is the first book you read. Get The C Programming Language from K&R, spend a couple weeks learning the most basic concepts, then move on to this book to learn how to actually use and build software with C which K&R won't teach you.
