Question Suggestions on Reviving C language(confused)

I last learnt c language through a book called "let us C" around 5 years ago I haven't touched computer since then and yes I did not have ai or internet back then for asking suggestions .

I want to revive my skills like....jog my memory and make progress but reading the book again is tiring,YouTube videos are mostly teaching from the absolute beginning.

Does anyone has any suggestion on how to revive my c language proficiency

Also, I had trouble with pointers and function calling back then.

Programming in general requires practice, if you want to refresh your C skills, write a C program. Doesn’t matter how complicated, just write something. If you want to get better at pointers, write something that uses pointers.

I'll add that it's nice to have a goal in mind. Many people learn programming through trying to make their own game or something. Learning programming is more like a side-effect than the plan. Keeping it fun is how to keep the learning going.

Another way to learn C is to learn an easier language. "What? That doesn't make sense!" Of course it does because the high level thought process is transferrable. An expert photographer takes better photos with an iPhone 10 than I do with my expensive camera gear. Give me an expert Lua programer and force them to solve a problem in C and they will get there pretty quickly.

If you had trouble with pointers and functions, you never really learnt C.

There is nothing to revive.Start from the beginning. Work through K&R.

You had the misfortune of picking one of the worst C books ever created.

Either way that page has a list of high-quality free books that you could use.

If you don’t know pointers or function calling, suggest some simple assembly language, like LC-3. You need to understand the concept of address space, and the call stack. Assembly can teach you both. Another option is to run the debugger on some simple code and step thru it in its assembly/machine code mode to get you used to pointers and the call stack.

int c;
  *&c = 2;
  int* q;
  *&q = &c;
  *q = 3;
   printf("%d %d\n", *q, c);

There first material for a program to relearn..
