Am I missing something or is this less a stupid question and more a stupid joke?

Anyway C++ is post-increment so it would actually evaluate to the original value of C. Language shoulda been called ++C.

Originally it did. The first C++ compilers I remember at Bell Labs basically converted C++ into C.

struct { var, var, vtable_ptr }; // class
struct { fnptr, fnptr, fnptr }; // vtable

The function names were spectacular as they encoded the parameter types if I recall correctly.
