How should I learn C++ when I only know Python and Javascript?
You should learn c# instead
by reading a book and writing code, silly

Don't learn c++ you fag
Download or buy a book, I recommend "C++ Primer" 5th edition

Learn pure c first. Once you realize how much more of a pain in the ass it is you can start learning c++.
Start with loops and control structures, then move to data structures and objects.

read a tutorial or a book
Javascript knowledge will help you somewhat
