Object-Oriented Programming Key Ideas Class Inheritance Polymorphism Early and Late Binding Virtuality override final Template method Destructor Interfaces Liskov substitution principle /destructor Slicing ShadowingPolymorphism Polymorphism (poly morphs) is the characteristic of an object to behave differently at run time. Polymorphism ▪ Inheritance is the base of polymorphism ▪ Enables separation of the interface and its implementation is one of the crucial ideas of modern software design.Object-Oriented Programming Key Ideas Class Inheritance Polymorphism Early and Late Binding Virtuality
