Cel is an object-oriented prototype-based programming language based on Self and Smalltalk. As of 2004 it is no longer being supported or developed. The author has referred people interested in Cel to the similar Io programming language. Self is an object-oriented programming language based on the concept of prototypes. ... Smalltalk is a dynamically typed, reflective, object oriented programming language designed at Xerox PARC by Alan Kay, Dan Ingalls, Ted Kaehler, Adele Goldberg, and others during the 1970s. ... 2004 is a leap year starting on Thursday of the Gregorian calendar. ... Io is a pure object-oriented programming language inspired by Smalltalk, Self, Lisp and NewtonScript. ...
Prototype-based programming is a style of object-oriented programming in which classes are not present, and behaviour reuse (known as inheritance in class-based languages) is accomplished through a process of cloning existing objects which serve as prototypes.
Prototype-based programming is often associated with particular schools of thought in cognitive psychology which emphasize prototypes or exemplars as key attributes of the learning process.
In the case of the Selfprogramminglanguage, much development time has been spent on the development of compilation and interpretation techniques to improve the performance of prototype-based systems versus their class-based competitors.
The C programminglanguage is a general purpose language which was originally designed for use on the Unix Operating System by Dennis Ritchie.
Then the program calls the printf function in the header file: stdio.h and passes it the values to be printed.
In this case, due to the format options we gave, the C program assumes that the value stored by the variable result is a decimal Number [Specified by d] and displays the output i.e.
