If you are interested in the graphical interfaces, read books about Qt. Then, if necessary, we can delve into the language.
If you are interested in programming in C++, in principle, read Myers. You should start with this
book. Maybe the first time do not everything will be clear, but it will set the direction for further development. Then it should read "Effective modern C++: 42 guidelines for using C++11 and C++14" - there are already about modern language standards.
