Hey there,
I’m doing some mainlining stuff for Linux phones, so it’d be helpful for debugging to know C.
Sometimes I just have to figure out what a driver does that makes it fail, which is hard without really understanding the syntax.
So the question is: What are some good resources for learning C?
I mean, I roughly know what a variable or function is, as I’ve played with Arduinos before. I don’t need an explanation that covers what programming is, but I also don’t know enough to pogram an Arduino without googling the most basic syntax all the time.
I prefer guided stuff that makes me type and think over just reading specs as purely reading specs does not mean it’ll stay in the head.


For books, I got more use from Harbison & Steele’s C: A Reference Manual than K&R. It has been a long time, though, so it’s possible that a great new book exists now.
For online, I recommend bookmarking this site: https://cppreference.com/w/c.html
