How do you implement an interface in C++ without an abstract class?
I know at least three ways, one of them involves variadic macros.
You don't even need to look that far, take any sufficiently aged library, like OpenGL.
It was rhetorical.
Yet I still had an urge to explain an obvious thing. Because it's C++, so everyhing goes. There are even tools to auto-generate C++ interfaces, because of course someone decided that C++ is inadequate and must be improved using some kind of poorly-documented ad-hoc extension language on top of C++.
