Doubt on virtual functions

[novino]

Class A inherits from B
B inherits from C
C inherits from D

Now D has 2 pure virtual functions x() and y(). i.e.
class D
{
x() = 0;
y() = 0;
}

Function x() is defined in Class C
Function y() is defined in both Class B and Class C

Now A is instantiated and object of class A calls function x(). i.e.
A aObj = new A;
aObj->x();

The call comes to the function defined in Class C
C::x()
{
.....
y();
}

Now y() is implemented both in class B and C.
At this point of time can anyone tell ideally where the flow should go. i.e.
C::x() will call C::y() or B::y() ?

The result i got from logs was quite different from what i was expecting, so if someone can give a proper explanation it would be appreciated

Thanks in advance.

B::y() will be called. The way I think about it is that the `this' pointer passed to C::x is a pointer to a base class, so you'll get a virtual dispatch when it calls y().

Does that make any sense?
