The world runs on code written in the C programming language, yet most schools begin the curriculum with Python or Java. Effective C bridges this gap and brings C into the modern era—updated to the latest C23 standard. With the aid of this instant classic, you’ll soon be writing professional, portable, and secure C programs to power robust systems and solve real-world problems.

Robert C. Seacord introduces C and the C standard library while addressing best practices, common errors, and open debates in the C community. Developed together with other C standards committee experts, Effective C will teach you how to debug, test, and analyze C programs. You’ll benefit from Seacord’s concise explanations of C language constructs and behaviors, and from his 40 years of coding experience.

Reviews 

Reviews from the 1st edition:

"This book's emphasis on the security aspects of C programming is unmatched. My personal recommendation is that, after reading it, you use all of the available tools it presents to avoid undefined behavior in the C programs you write."
—Pascal Cuoq, Chief Scientist, TrustInSoft

"This book contains a rich amount of quality information on the C language and programming. It’s clearly written, with good, pithy examples…an excellent book. Highly recommended."
—David Sullivan, ACCU's {CVU} Magazine

"An excellent introduction to Modern C."
—Francis Glassborow, ACCU

"A really, really good C book that does not talk down to you."
—Stephan Neuhaus, @stephanneuhaus1

"An updated and relevant version of what you may be coding. I'm a fan."
