Eiffel is an ISO-standardized, object-oriented programming language designed by Bertrand Meyer ( an object-orientation proponent and author of Object-Oriented Software Construction ) and Eiffel Software.

The design of the language is closely connected with the Eiffel programming method.

New language design ideas, particularly through the Ecma / ISO standardization process, continue to be incorporated into the Eiffel language.

The key characteristics of the Eiffel language include:

The design goal behind the Eiffel language, libraries, and programming methods is to enable programmers to create reliable, reusable software modules.

Four other open source implementations are available: " The Eiffel Compiler " tecomp, Gobo Eiffel, SmartEiffel — the GNU implementation, based on an older version of the language — and Visual Eiffel.

The SmartEiffel team has turned away from this standard to create its own version of the language, which they believe to be closer to the original style of Eiffel.

To put it in the language of other object-oriented programming languages, all Eiffel fields are " private ", and " setters " are needed to modify values.

* Eiffel Encryption Library: Open source cryptography library for the Eiffel language

* EiffelStudio, a development environment for the Eiffel programming language

* Eiffel ( programming language ), developed by Bertrand Meyer

Java applets were introduced in the first version of the Java language in 1995, and are written in programming languages that compile to Java bytecode, usually in Java, but also in other languages such as Jython, JRuby, or Eiffel ( via SmartEiffel ).

It is probably best to view it as an object-oriented language, with many ideas borrowed from Eiffel.

* EiffelStudio for the Eiffel language

The term was coined by Bertrand Meyer in connection with his design of the Eiffel programming language and first described in various articles starting in 1986 and the two successive editions ( 1988, 1997 ) of his book Object-Oriented Software Construction.

* SCOOP ( software ), the Simple Concurrent Object-Oriented Programming extension for concurrent programming in the Eiffel programming language

* EiffelStudio for the Eiffel programming language

Genericity facilities have existed in high-level languages since at least the 1970s in languages such as CLU and Ada, and were subsequently adopted by many object-based and object-oriented languages, including BETA, C ++, D, Eiffel, Java, and DEC's now defunct Trellis-Owl language.

BETA is a strongly typed language like Simula, Eiffel and C ++, with most type checking done at compile-time.

While Eiffel does not allow direct access to the features of a class by a client of the class, it does allow for the definition of an " assigner command ", such as:

* September – High definition television broadcasts are sent from a new 30 kW ( peak power ) transmitter below the Eiffel Tower in Paris.

The Director of Documentation for what was then the Société nouvelle d ' exploitation de la tour Eiffel ( SNTE ), Stéphane Dieu, commented in January 2005, " It is really just a way to manage commercial use of the image, so that it isn't used in ways we don't approve.

As a global landmark, the Eiffel Tower is featured in media including films, video games, and television shows.

Indicate location-Establishing shots may use famous landmarks to indicate the city where the action is taking place or has moved to, such as the Empire State building or the Statue of Liberty to identify New York, the London Eye or Big Ben to identify London, the Sydney Opera House to identify Sydney, the Eiffel Tower to identify Paris, or the Las Vegas Strip to identify Las Vegas.

Compilers for computer programs written in Eiffel provide extensive optimization techniques, such as automatic in-lining, that relieve the programmer of part of the optimization burden while producing code whose efficiency is comparable to that of code written in C ++.

EiffelEnvision is a plug-in for Microsoft Visual Studio that allows users to edit, compile, and debug Eiffel projects from within the Microsoft Visual Studio IDE.

An Eiffel " system " or " program " is a collection of classes.

Unlike many object-oriented languages, but like Smalltalk, Eiffel does not permit any assignment into fields of objects, except within the features of an object, which is the practical application of the principle of information hiding or data abstraction, requiring formal interfaces for data mutation.

An upshot of this is that " setters " can, and normally do, implement the invariants for which Eiffel provides syntax.

He is best known for the world-famous Eiffel Tower, built for the 1889 Universal Exposition in Paris, France.

His name is one of the 72 names inscribed on the Eiffel Tower.

* 1908 – A long-distance radio message is sent from the Eiffel Tower for the first time.

He is considered the father of spaceflight and the first person to conceive the space elevator, becoming inspired in 1895 by the newly-constructed Eiffel Tower in Paris.

* 1889 – The Eiffel Tower is officially opened to the public at the Universal Exposition in Paris.

* 1889 – The Eiffel Tower is officially opened.

The current tower is at least the second Eiffel Tower replica built in Paris ; the first was constructed of wood and later destroyed by a tornado.

Even the name is inspired by Eiffel ; the Sather Tower is a recognizable landmark at Berkeley, named after Peder Sather who donated large sums to the foundation of the university.

" They clearly have known better times, a visit to the Eiffel Tower and grape-harvesting by the Rhône ; it is about all either has to say about their pasts.

A number of pre-altered graphics packages were distributed, including some which replaced the reward buildings with images of various well known international buildings, such as the Eiffel Tower, but most buildings were made by fan-artists and shared on the Internet.

Eiffel 65 is an Italian three-piece Eurodance group formed in 1998 and best known for pioneering in pitch correction and Auto-Tune, and for their international hit " Blue ( Da Ba Dee )".

The first year's events were small, but in 2004 the holiday gained international support from a group of French performers, who staged elaborate ninja poses in front of famous landmarks ( such as the Eiffel Tower ).

* Taipei 101 ( Taipei 2004 )-while not yet featured in a major international film as of 2004, in local productions it is fast becoming an Eiffel Tower-like cliché that the view from every Taipei apartment includes Taipei 101.

Barra also has replicas of many international architectural icons like the Leaning Tower of Pisa, the Tower Bridge of London, and the Eiffel Tower of Paris ( all found in the Barra World Shopping Center ).
