Think of the Linux kernel. That's a huge project, organized in an object oriented fashion. Is there a difference between this->method(arg) and method(this, arg)?
So yeah, it works fine, just more verbose cause it lacks some syntactic sugar. I prefer C for simple or high-performance programs, and I can see why people might want C++ for larger ones. Problem is some people make a mess pulling out all the stops in C++ OOP features.
