virtual function in parent of parent class [duplicate]

Question

The following code is late binding test() method but shouldn't it bind early? because test() method is not virtual in class B(but in class A), and we are using pointer of class B.

class A{
    public:
        virtual void test(){
            cout<<"test a";
        }
};
class B : public A{
    public:
        void test(){
            cout<<"Test b";
        }
};
class C: public B{
    public:
        void test(){
            cout<<"test c";
        }
};
int main(){
    B *bp;
    C objc;
    bp = &objc;
    bp->test();  // test c
}

Answer 1

Once a function has been declared virtual in a class, it's always virtual in the classes that inherit from that class, whether you use the virtual keyword or not.

So in your class C, the test() function is actually overriding B and A's own test() functions.
