Memory layout of an object with multiple inheritance

[stasgrom]

Guys, I have this situation: the class C is defined as follow:

class C: public A, public B {...};

Now when I create an object of class C, I can see that the compiler (VS
8.0) decides to layout the memory of this object so that the fields of
class B come before the fields of class A. I always thought the layout
is defined by the order of inheritance. Was I wrong?

Thanks.

Yes, you were wrong. It's implementation defined.
