So after getting some free time, I decided to try and revive my forgotten C++ knowledge. I also tried searching for helpful videos on how to use C++, but all of them are either paid or not very good. I found the new boston, which looks promising, but a lot of people are saying that he teaches bad programming habits, skips some stuff, doesn't tell you WHY some things work the way they do and so on. I also re-discovered ReelLearning, which I used before and I've slightly benefited from it, but people have also somewhat said the same thing about him as well.
So to summarize, after a lot of searching, I came up with nothing and decided to use the tutorial in this site for remembering everything I've forgotten and learning new stuff. So, is the tutorial here actually good for this? Or just for referencing?
Also I wanted to ask if there are any good books for modern C++? I found a free one from O'Reilly - "Practical C++ Programming", but it was pretty old, I think it was using C++95 or sth. Are there any good books (preferably free) that explain C++11 and 14 from the ground up like this one:
