Did u know? How the problem of duplicate sub-objects is resolved?
The problem of duplicate sub-objects is resolved with virtual inheritance. When a base
class is inherited as virtual, only one sub-object will appear in the derived class—a process

void get (int);

void show (void);
};
void A :: get (int a)
{ x = a; }
