POLYMORPHISM

Q: What is Polymorphism??
A: Polymorphism allows a client to treat di_erent objects in the same way even if they were
created from di_erent classes and exhibit di_erent behaviors. You can use implementation
inheritance to achieve polymorphism in languages such as C++ and Java. Base class object's
pointer can invoke methods in derived class objects. You can also achieve polymorphism in C++
by function overloading and operator overloading.

Q: What is problem with Runtime type identification?
A: The run time type identification comes at a cost of performance penalty. Compiler maintains
the class.

Q: What is Polymorphism?
A: Polymorphism allows a client to treat different objects in the same way even if they were
created from different classes and exhibit different behaviors. You can use implementation
inheritance to achieve polymorphism in languages such as C++ and Java. Base class object's
pointer can invoke methods in derived class objects. You can also achieve polymorphism in
C++ by function overloading and operator overloading.
