Next book after "Programming: Principles and Practice Using C++ (2nd Edition)"

[etrusks]

Hi, could anyone recommend good book to read next after ill be finished with "Programming: Principles and Practice Using C++ (2nd Edition)". Also on what things i should focus the most (templates, standard library, OOP, ...) if i would want to eventually find someone who would like to hire me on some C++ projects.

I wouldnt want to work on pretty and shiny GUIs but more on the core of the programs. So yea advices where to go next after this book would be very appreciated

Also would love to understand how this programming stuff is connected with servers, internet and incoming, outgoing data. Yes im not very good at understanding it now but i'll learn untill i'll understand it all. So books about this stuff and how its connected with C++ would be also cool :)

Thank you very much for reading!!
