Anyone know good resources for my friend to learn C?

Dont learn c unless you absolutely have to... Imho

The C Programming Language, by Kerninghan & Ritchie is a must have. Learn-C.org is a decent resource. Udemy has C Programming for Beginners. C is a great beginning language.

K&R C (Kernighan and Ritchie) is useful. I found Zed Shaw's "Learn C the Hard Way" (https://learncodethehardway.org/c/) to be VERY useful, well written, and helpful.

My best advice is to start with "Learn C the Hard Way," use K&R C as a reference, and to come up with some sort of interesting project idea as early as possible to provide incentive to learn more.

CS50x, online course hosted by Harvard on Edx. Not sure if it's still going for free but it started me on the path to where I am today. Can't recommend enough.
