Writing a C Compiler Build a Real Programming Language from Scratch

A hands-on, example-filled guide to the theory and practice of writing a C compiler: a computer program that translates code written by programmers into code the computer can read.

An approachable, hands-on tutorial to writing a C compiler: a computer program that translates code written by the programmer into code the computer can understand. By building a compiler, readers will gain invaluable knowledge about how programming languages work; knowledge that will make them better programmers. Readers are gently led step-by-step to build a small working compiler and will develop throughout the book. Writing a C Compiler offers readers an accessible, practical approach to this complex and often overly theoretical topic.

Nora Sandler is a software engineer based in Seattle. Her interest in compilers dates back to her time at the University of Chicago, where she researched parallel programming languages with the Manticore Project. More recently, she's worked in the computer security industry developing compilers for domain-specific languages.
