A lot of C++ books are more for people that know basic C++ and most of the syntax. I personally recommend https://www.sololearn.com/Course/CPlusPlus/ for learning C++'s syntax and basic operations (It's on the app store too, you can download it to your phone and also run basic c++ code on your phone). Play around with what you learn and make some basic things like a calculator. When you are done with that course, I'd then suggest getting into a modern C++ book that is well written and making more complex programs. The most important thing is to make sure you learn MODERN c++, not old C++.
