An array stores a fixed-size sequential collection of
elements of the same type.

- 9. Inheritance One of the most important concepts Inheritance allows us to define a class in terms of another class makes it easier to create and maintain an application Base and Derived Classes
- 10. Example
- 11. C++ logic In C we had to code our own bugs. In C++ we can inherit them.
- 12. C# - Polymorphism The word polymorphism means having many forms 'one interface, multiple functions'. Static (In static polymorphism, the response to a function is determined at the compile time) Dynamic(In dynamic polymorphism, it is decided at run-time.)
- 13. Static Polymorphism C# provides two techniques to implement static polymorphism. Function overloading Operator overloading Function Overloading You can have multiple definitions for the same function name in the same scope
- 15. Dynamic Polymorphism C# allows you to create abstract classes that are used to provide partial class implementation of an interface Abstract classes contain abstract methods The derived classes have more specialized functionality. rules about abstract classes You cannot create an instance of an abstract class You cannot declare an abstract method outside an abstract class When a class is declared sealed, it cannot be inherited, abstract classes cannot be declared sealed.
- 16. Example
- 17. Polymorphism Fact A dog, a spider, and a human can all walk at a rate of speed. Everyone knows this. But, when talking about the specifics of how they walk, each implementation is different. A spider has 8 legs and will 'scurry' around very quickly ( relative ). A dog has 4 legs and will leap and jump and run around. A human has 2 legs and will place one in front of the other, enabling them to walk.
