The duplication of inherited members due to multiple paths can be avoided by making the common base class(ancestor class) as virtual base class..

FOR EXAMPLE

class A //grandparent
{
...
...
};
class B1:virtual public A //parent1
{
...
...
};
class B2:public virtual A //parent2
{
...
...
};
class C :public B1,public B2
{
... //only one copy of A
... //will be inherited
};


When a class is made a virtual base class, it take necessary care to see that only one copy of that class is inherited, regardless of how many inheritance paths exits between the virtual base class and a derived class.
