Answer / vaibhav panchal
A virtual class is an inner class that can be overridden by
derived classes of the outer class.
eg.
class Base
{
public:
int value
};
class child1 : public Base { };
class child2 : public Base { };
class grandchild : virtual public child1, virtual public
child2
{
public:
grandchild() { value };
};
