  What is Elica?What is Natural OOP? Concepts and features of NOOP Comparison with traditional OOP
• 10.
  Elica One ofthe 160+ Logo dialects Flexibility to the extreme ing names and code at run-time Dynamic modification of objects Experimenting with different programming styles 3D graphics, animation, modeling Natural OOP
• 11.
  OOP and NaturalOOP OOP collection of concepts, tools and styles requires changes in language syntax (C, Pascal, Logo) complex terminology (class, instance, inherit, method…) Natural OOP extended collection of concepts, tools and styles no changes in language syntax no special data structures for OOP elements no special procedures and functions to manage OOP no new terminology

  OOP vs NOOPExample Problem: Make class POINT with fields and Y and method. using OOP using NOOP to p oint :x :y to distance output sqrt :x*:x+:y*:y end e nd type TPoint = class fx : integer; fy : integer; public constructor Create(x,y:integer); function Distance:real; end; constructor TPoint.Create(x,y:integer); begin fx:=x; fy:=y; end; function TPoint.Distance:real; begin Result:=Sqrt(fx*fx+fy*fy); end;

  NOOP NOOP itselfis like an evolution: Classes  species Instances  individual creatures Fields  characteristics Methods  behaviour Inheritance  genealogical relations

  Object Creation Creatingan object is like giving birth to a creature This is a common metaphor in all OOPs An creature in Nature can be born in many ways – agamic reproduction, sexual reproduction, cloning, etc Most OOP support only one way of creation
• 15.
  Creating by Assignment The most primitive creatures on Earth reproduce themselves by fission ( agamic reproduction ). Technically, this means creating a creature as an exact copy of another one. MAKE "PETER :TOM
• 16.
  Identification of ObjectsTwo methods for identification of objects: (lack of instanceOf( ), className( ), etc…) A local variable containing the name of the class corresponds to creatures that know what they are , like dolphins and maybe … humans. Recognition by properties is related to more primitive creatures that recognize themselves by the smell and other senses.
• 17.
  Inheritance Supported aresingle inheritance (for partheno-genesis species ), and inheritance from two parents . There is also multiple inheritance ( adoption ) and conditional inheritance ( guardianship ).

  The Big QuestionIf the Elica core is soooo small… and a functionality like adding two numbers is not hardcoded in the system but is implemented as a user-defined library… and all this Natural OOP is so human friendly that it gives hard time to the translator… well, how could a system like this be used to do some REAL PROGRAMMING ???
