Are you suggesting C++ lacks available libraries? Because for all of its faults, lack of libraries is not one I've run into.
Many desktop and server applications are still written in C or C++, including the Web browser I'm writing this on. Reports of their deaths are exaggerations.
Unfortunately, many programming tutorials are written by an intermediate for a beginner. This means they can only take you so far. Thankfully, C++ is so old that there are quite a few superb books on both the language (and it's many pitfalls) and applying the strengths to build large scale, maintainable programs.
