How I Start: C++

Yes, eventually you will probably want to figure out how to do cross-platform development. But if you really want to just learn the C++ language, I would start with an actual IDE, such as Visual Studio or Xcode, and just stick to one platform.
Or better yet, just use an online environment such as cpp.sh or ideone.com or codechef.com.
This is why I make it clear at the beginning that the article isn't meant to be an introduction to the language (non-goal!) and also point out references for a beginner to learn from later. I also mention that learning a single IDE first and learning it well is a good idea.
