There are programmers who have never used C before! This is a shocking fact to me, as C is where I started programming. And there are many programmers who want to learn to use C, but already know how to program. C for Beginners is easy to find with a Google search. They need an introduction to pointers and a bit of malloc. Hopefully without mentioning things like functions, types, and how to write a conditional which would surely put a ruby, python, or java programmer to sleep.
So here it is. A few code examples with pointers. I mention tools like gcc and some flags and gdb. And there is some assembly code, as really writing C requires some computer architecture understanding.
Or here’s a document with the same goals from Stanford: Stanford CS Education Library: 102
