When I got into C++ several years ago, I read "A Tour of C++" by the creator of C++, Bjarne Stroustrup, and thought it was quite good:

The second edition is from 2018 and uses modern C++ (C++17). So, I would say read that and then write a bunch of C++ code to learn by doing.

Better question, what problems/scenarios would you try to solve with c++??

I would recommend the book "C++ Crash Course" by Josh Lospinoso.

It covers modern C++ through C++ 17 and is well written and easy to understand.
