Too many of the video tutorials are horrible. Very outdated and wrong information, and when they get the information correct the video really doesn't give clear and easy to understand examples.
An online (written) tutorial. not updated in a while though, is right here at CPlusPlus:
http://www.cplusplus.com/doc/tutorial/
Another online tutorial that is frequently updated is:
https://www.learncpp.com/
While the following link is a bit outdated it does provide good ideas about what types of C++ books to buy. Yes, BOOKS. Not just one.
https://isocpp.org/wiki/faq/how-to-learn-cpp#buy-several-books
Do understand that most books, especially beginning books, don't use the latest language standard. Currently that standard is C++17.
C++11 made some radical changes to what can be done and how code is written compared to how things used to be done. Lots of new features that most school/university courses don't address.
C++14 didn't make a lot of changes, IMO mostly minor fixes.
C++17, which I am still trying to get a firm grasp of, is almost as much of a change as C++11 was. Lots of new features to drool over.
What is proposed for C++20 (or whatever it called when 100% finalized) will be more to learn. Retraining will never cease. ;)
Two reference sites for the C++ language, NOT for learning C+++:
1.
http://www.cplusplus.com/reference/ (sadly it appears to no longer be updated)
2.
https://en.cppreference.com/w/ (This is updated, but is not the easiest format for a beginner)
There are examples with most of the language features at the reference sites. Copy'n'paste the examples into your compiler. See what they do. And then "play around" by rewriting the code and extending what you think the examples do.
As you learn by coding your own examples you can always post code here and ask questions.
Demonstrate you want to learn by writing code, and sharing it, will get help from some very knowledgeable people. Both experts and others learning.
Expect to get frustrated when code you write and adapt don't work the way you expect.
Learn how to debug code.
And if possible use more than one compiler. If you are a Windows user, Visual Studio Community. And a GCC variant. Learn how to use command line compilation, and and IDE.
I am a long time self-taught programming hobbyist. All of what I know is from books and tutorial websites.
And writing a LOT of code.
Not formal training, no programming job.
