Between the two sits the compiler: the program that turns one into the other. This article explains what a compiler is, where compilers came from, how each of their phases works, how a C file becomes an executable on a real system, and how to build a small compiler of your own. Every compiler output shown here was produced by running the tools on Ubuntu 22.04 with GCC 11.4 and Python 3.10, not written by hand.</p>
