Accessing a member/method of a virtual derived class

The example here doesn't make sense, but this is basically how I wrote my program in Python, and I'm now rewriting it in C++. I'm still trying to grasp multiple inheritance in C++, and what I need to do here is access A::a_print from main through the instance of C. Below you'll see what I'm talking about. Is this possible? ``` #include <iostream> using namespace std; class A { public: void a_print(const char *str) { cout << str << endl; } }; class B: virtual A { public: void b_print() { a_print("B"); } }; class C: virtual A, public B { public: void c_print() { a_print("C"); } }; int main() { C c; c.a_print("A"); // Doesn't work c.b_print(); c.c_print(); } ``` Here's the compile error. ``` test.cpp: In function ‘int main()’: test.cpp:6: error: ‘void A::a_print(const char*)’ is inaccessible test.cpp:21: error: within this context test.cpp:21: error: ‘A’ is not an accessible base of ‘C’ ```
