This is purely a theoretical question, I know that if someone declares a method private, you probably shouldn't call it. I managed to call private virtual methods and change private members for instances, but I can't figure out how to call a private non-virtual method (without using __asm). Is there a way to get the pointer to the method? Are there any other ways to do it?
EDIT: I don't want to change the class definition! I just want a hack/workaround. :)

Private: The class members declared as private can be accessed only by the functions inside the class. They are not allowed to be accessed directly by any object or function outside the class. Only the member functions or the friend functions are allowed to access the private data members of a class.
Yes, we can declare the main method as private in Java. It compiles successfully without any errors but at the runtime, it says that the main method is not public.
Private Methods can only be used inside the class. To set private methods, use the private access specifier. Private access specifier allows a class to hide its member variables and member functions from other functions and objects. Only functions of the same class can access its private members.
See my blog post. I'm reposting the code here
template<typename Tag> struct result { /* export it ... */ typedef typename Tag::type type; static type ptr; }; template<typename Tag> typename result<Tag>::type result<Tag>::ptr; template<typename Tag, typename Tag::type p> struct rob : result<Tag> { /* fill it ... */ struct filler { filler() { result<Tag>::ptr = p; } }; static filler filler_obj; }; template<typename Tag, typename Tag::type p> typename rob<Tag, p>::filler rob<Tag, p>::filler_obj; Some class with private members
struct A { private: void f() { std::cout << "proof!" << std::endl; } }; And how to access them
struct Af { typedef void(A::*type)(); }; template class rob<Af, &A::f>; int main() { A a; (a.*result<Af>::ptr)(); } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
