Does anybody know of any great instructors who teach C programming that are as great as Mosh or better than Mosh? I only ask because I see Mosh doesn’t offer any C courses. He offers C# courses, which is not what I’m looking for.
If you are still interested, then maybe you should check out the Harvard’s cs50 introduction to computer science on EdX. It’s a mix of languages but C is used through at least half of it. It should be enough to get you going. Also, if you check out the MagPi website, there are some free mini books on working with C and creating GUIs with it.
