Almost 50 years ago, the C language defined modern computer programming. This book shows you why C is still as powerful and popular as ever, with an inside look at the new C23 standard.

For programs that need to be small, fast, and unfailingly reliable, C is still the gold standard. Whether you're writing embedded code, low-level system routines, or high-performance applications, C is up to the challenge. This unique book by Jens Gustedt, a member of the ISO C standards committee, gets you up to speed with C23.

In Modern C, Third Edition you'll:





Learn C basics, core features, and advanced concepts
Leverage major C23 improvements for security, reliability, and performance
Write portable code that runs anywhere
Build multi-threaded applications with atomics and synchronization
Create robust and resilient software with error handling
Use type-generic programming for reusable code


C powers more software than any other language—from embedded devices to distributed systems. In Modern C, Third Edition you'll learn to harness C's full potential using the latest tools and techniques. After a quick review of the fundamentals perfect for beginners or coders who haven't used C in a while, this book guides you to mastery of C23, the latest ISO standard.
