C++ is cross-platform. You can use it to build applications that will run on many different operating systems.

What is not cross-platform is the compilers that translate C++ into object code. No single compiler, to my knowledge, has all the necessary features so that when you use it to compile a C++ program, it will automatically run on Windows, Linux and Mac OS.

Qt Creator is integrated with multiple compilers and has build automation. It makes it easy to switch between different setups and target platforms. It provides support for building, running and deploying C++ applications not only for desktop environments but also for mobile devices.
