C++ in Linux or Windows

>inb4 Google, I looked and couldn't find what I'm asking about

Is it better to code C++ programs in Linux or Windows? I'm new to this. I'm just learning and don't want to start off on the wrong track. I'm using Linux btw.

Couldn't you just take the same code written on Linux and compile it on Windows? The only difference would be certain OS-specific differences like window managers, etc., which could somewhat easily be fixed, right? If so, what's the big deal about porting programs to and from Linux and Windows? What am I missing?

If you also have some brotips on better languages than C++, please share them. I want to be able to make all sorts of programs; efficiency is important. My ideal language is one that can do "anything" so that I can specialize in a master race language. Tl;dr Please confirm whether C++ is god tier.

Start off on the wrong track? You already have, if youre using C++. Use C, honestly, is will put things in your way that _need_ to be in your way for you to structure a program right, such as using structures for different types, where C++ gives you the ``answer'' with inheritence, C causes you to actually think, and therefore it is harder to end up with sphaghetticode. Shitch to C now and you won't regret it. Also, you don't need to worry about portability because fuck windows. Development is better in Linux anyway.
