Beej's Guide To C Programming

This is an intro to C for folks who already know how to program in another language. The first half of the book is written in a tutorial style, while the second half is a reference section complete with examples (inspired by the incomparable Turbo C Bible). The goal is to keep this up-to-date with the latest C standards.

This guide assumes that you've already got some programming knowledge under your belt from another language, such as Python, JavaScript, Java, Rust, Go, Swift, etc. (Objective-C devs will have a particularly easy time of it!)
