// multiple inheritance in C++

using namespace std;
#include<iostream>

class A
{public:
  virtual void f() {cout << "A.f\n";}
};

class B
{public:
  virtual void f() {cout << "B.f\n";}
};

class C : public A, public B   // no error here, compiler error in C#/Java
{};

// no compiler error or warning so far.

// Keep in mind that "main" is usually in a separate file and is
// COMPILED SEPARATELY from the other classes.

int main()
{
  C *n = new C();  // no error here
  // n->f(); // will give compiler error about ambiguous f 

  A *n2 = new C(); // static type A, dynamic type C
  n2->f();         // will print A.f:  smart!
  
  B *n3 = new C();
  n3->f();         // will print B.f:  what did it use to figure this out?

  return 0;
}

// But what if A and B both implemented functions f and g, and I wanted
// to inherit f from A and g from B?????
