To Remove the ambguity problem in multiple inheritance we
make the base class as vitual that means it will make only
one copy its common data member.

EX: suppose we have a base class A , which have a data
member x as integer.

class b: virtual public A
{
};
class C : virtual public A
{
};
class d: public B,public C
{
}

without making classes A and B as virtual class d had two
copies of x.This will arised ambguity problem.
