A detailed introduction to the C programming language for experienced programmers. 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--covering the modern C17 Standard as well as potential C2x features. 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. You'll learn: How to identify and handle undefined behavior in a C programThe range and representations of integers and floating-point valuesHow dynamic memory allocation works and how to use nonstandard functionsHow to use character encodings and typesHow to perform I/O with terminals and filesystems using C Standard streams and POSIX file descriptorsHow to understand the C compiler's translation phases and the role of the preprocessorHow to test, debug, and analyze C programsEffective C will teach you how to write professional, secure, and portable C code that will stand the test of time and help strengthen the foundation of the computing world.
