The Unofficial C For Dummies Website

This page supports the C programming books written by Dan Gookin, as well as the C language training courses offered online at LinkedIn Learning. All coders are welcome.

I have been unwillingly retired from my book-writing and online-training careers, thanks to AI. Hopefully, I will create more material in the future. Even so, this site will remain active through 2029.
