Hi,

What is the best way to learn C from scratch? I used to code C in high school, but haven't touched for 14 years since.

Any suggestions to find anything qualifying as "from scratch" course?

EDX has a lot of free courses that are based on real university courses - not so good though if you want a "credible" citation on a resume though.

I learned it 30 years ago reading the standard K & R book a couple of times, and never forget it, altough I'va been programming for the last 2 decades.

EDIT. https://en.wikipedia.org/wiki/The_C_Programming_Language

Online PDF: https://www.dipmat.univpm.it/~demeio/public/the_c_programming_language_2.pdf Not the latest édition though...

There must be more complete recommendation, but this could be a easy & useful first step.

There must be plenty of tutorials on uTube.

Thks 4 ur attention.

K&R is a good book, but it's somewhat concise: best for at least moderately experienced programmers. I also learned C over 30 years ago from K&R, but at the time I was writing production code in FORTRAN, PL/I, and (I swear) IBM 370 Assembly Language (and also avoiding COBOL like the plague). For a more thorough text for beginners, I'd recommend C Primer Plus by Prata. But there's something else you need to do: find something real and substantial to do with it. Working the textbook examples is a good start, but that doesn't really cause it to sink in the same way that actually using a language in practice does.

John, you're right saying practice remains the key, but I guess nikulinpi has a good purpose for learning C.
As I was coming from BASIC, it helped be to think closer to hardware.

Long side note: Funny you're mentionning your attitude towards COBOL as I had the same, for which I had a few regrets with all the supposed easy money to be made out of it in the late 90's.

Thks 4 ur attention, interest & support.

My first programming language was ALGOL in school almost 50 years ago. It was a traumatic experience, but I realise now that it was a good language...
Then FORTRAN IV for some years (I liked it).
Then PL/1 (a very good language, that should have replaced both FORTRAN and COBOL), but I think IBM did some mistakes there in pricing. Customers had to buy a license just to run a compiled program, stupid. IBM also had a language for scripts REXX that looked like PL/1. (emerge dev-lang/regina-rexx :) ).
My last languages were C and C++. They gave me grey hair! I wrote some programs to run under unix, but I used Windows Visual C++ to write and test them. I think Visual C++ is free to use for students. :)

After myself, the next biggest hurdle I've encountered are example after example which are then followed by some statement to the effect of "but don't do that in production" (because it was only for "learning" purposes, and is very flawed). Well, OK. But that doesn't truly help me learn. I'll look into the reference. Thanks.
