I want to learn C language, where do I start?

Question

OOP

Good day to all.
A question for connoisseurs and seasoned programmers.
I am a frontend developer, I know HTML / CSS / JS, but I realized that my soul does not lie with them, I want to do some serious coding.
I decided to start with the C language, or rather, I already started studying from Head First books, I think to program for six months and smoothly switch to C ++ or Java. Let's just say, first go through "special training", then to rush into battle.
But to be honest, I don’t know how to systematize and break down language learning into a sufficient number of small goals. It was easier to break the layout into groups for learning, just like English, for example:
1) Grammar
1.1 Present tense
1.2 Future tense
1.3 Past tense
... etc
When you have such a list, and along the way you overcome it, the joy of studying is much greater, and it is remembered better than when you study everything in a row. For the C language, I couldn’t come up with something like that, so I ask for help, I’m not too strong in such abstract languages. I think it will be useful for other beginners, thank you all.

Answer 1

From assembler. It is not necessary to learn it, but learning, for example, how to write data to a file will be very useful.
And then there is classical literature:
Kernighan B., Ritchie D. The C Programming Language

Answer 2

there are very good video tutorials "Programming in C (SI) (Specialist)", here is the link

Answer 3

I advise you to look for books by Stephen Prat. Everything is explained very well. There are both C and C++.

Answer 4

IMHO K&R.
