关于C++多重继承下虚表结构的问题

class ParentA {
public :
	int a=0x123456;
	virtual void vFunParentA(){
		std::cout << "vFunParentA" << std::endl;
	}
};
class ParentB {
public:
	int b = 0x456;
	virtual void vFunParentB() {
		std::cout<<"vFunParentB"<<std::endl;
		int i = 0;
	}
};
class Child:public ParentA,public ParentB {
	int c = 0x789;
};
int main()
{

	//注意这里使用void*
	void* pChild = new Child;
	//强转
	ParentB* pParentB = (ParentB*)pChild;
	//强转
	ParentA* pParentA = (ParentA*)pChild;
	
	pParentB->vFunParentB();
	pParentA->vFunParentA();

	getchar();
