C Head First is a really good book to learn from.

Are you referring to this eBook?

If so, It's certainly worth reading.

That is correct. I love that book and that's how I began completely understanding C. I didn't quite get it from other tutorials but the writer broke it down completely and now I effectively understand data types and memory management.

I've just started reading It, and It seems very beneficial.

It's definitely extremely well written.
