Having been trying to using this, but strangely found that there is no c++ version available for Windows, whereas it is the preferred version in linux. Is this the case?.
I'm not sure what you mean. The engine is written in C++. There is the standard build which comes with GDScript and the Mono build which also has C# support. Both support dynamic libraries. You can download the source and compile it very easily on any platform if that's what you're after?
All builds (except for server/headless build which is Linux only) are available for Linux, macos and Windows as binaries. This includes the standard build and the Mono build. All builds are also capable of loading dynamic libraries at runtime which you can write in C++.
I think you are misunderstanding. Just go to the webpage, select download, and from the windows tab download the "standard version" and you're good to go.
I don't even see what you mean by it being "a c++ available for linux". You got the same choices for all systems. Just download the editor/engine and start programming. No need to compile anything, except your own scripts/logic if you choose to use a compiled language.
I have done c++ Godot development on windows and Linux. They are equivalent. Only difference is the massive PITA that setting up your windows environment is. (Python, scons & msvc)
