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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | 1491903899 | | Best Sellers Rank | #228,813 in Books ( See Top 100 in Books ) #133 in Computer Hacking #611 in Computer Programming Languages #700 in Software Design, Testing & Engineering | | Customer reviews | 4.4 4.4 out of 5 stars (73) | | Dimensions | 17.78 x 2.34 x 23.34 cm | | Edition | 2nd ed. | | ISBN-10 | 9781491903896 | | ISBN-13 | 978-1491903896 | | Item weight | 653 g | | Language | English | | Print length | 406 pages | | Publication date | 11 November 2014 | | Publisher | O'Reilly Media | ## Images ![O'Reilly 21st Century C - Image 1](https://m.media-amazon.com/images/I/917RSEJ9j9L.jpg) ## Customer Reviews ### ⭐⭐ Review *by S***A on 26 May 2021* 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 *by P***S on 7 May 2019* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/320836911-oreilly-21st-century-c](https://www.desertcart.co.uk/products/320836911-oreilly-21st-century-c) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-03*
