Polymorphic “Classes” In Good Ol’ C

• bring C++

• C: implement by hand everything the C++ compiler does

• interface in c

  • func ptr type for each virtual

  • const method?

  • need .c file for vtable call implementation

    • init: vtable setup, called by base classes

• implementation

  • is-a -> containment

  • note: methods (incl. dtor) only used via base class and dynamic dispatch

    -> static in .c
