confusin with virtual inheritance

[mangesh]

considr following code

class V
{ };

class B1 : virtual public V
{};

class B2 : virtual public V
{};

class D : public B1 , public B2
{};

According to my understan B1 , B2 and D will each keep a pointer to V .
is it corect ?
can anyone suggest godd site/book for topic .

The class D will only have one instance of base class V as shown below

D
/ \
B1 B2
\ /
V

That is both B1 and B2 inherit the same V as part of D. Try not to
confuse pointers with inheritance as this will probably only lead to
greater confusion.
