  7. Function Overriding Use to describe virtual function redefinition by a derived class. . Useful when we want to have multiple derived classes implementing a base class function.

  8. Function Overriding . Put the common code to all of the derived classes in the base class function. Each of the derived class functions we can add the code specific to each one.

  9. Virtual Function Polymorphism can also be achieved at run time. . Polymorphism can also be achieved at run time This is done using the concept of virtual functions.

  10. Virtual Function Which class' function is to be invoked is decided at run time. And then the corresponding object of that class is created accordingly. This is also called as late binding.

  11. Example (Cont.) int main() base *p; base ob(10); derived d ob(10); derived1 d_ob1 (10); p-80b; p->func(); pe&dob ; p->func(); p-&d_ob1; p-func (); return 0;

  12. Abstract Class When a class contains at least one pure virtual function then it is called an abstract class.

  13. Point to be Remember class Animal{ public: /ipure virtual functions virtual void run() 0; virtual void eat() 0; If we derive a class from Animal base class then derived class will be forced to implement all functions. If we miss even a single pure virtual function to implement in child class then on object creation compiler will throw an error. .

  14. Thank You
