Program Development Language Field

FORTRAN Fortran is derived from the abbreviation of "Formula translation" (English: Formulatranslation), which is a programming language. It is the world's first high-level computer programming language, widely used in science and engineering computing field. Fortran language plays an important role in the field of numerical, scientific and engineering computing with its unique functions. Versions prior to Fortran 90 are known as FORTRAN (all uppercase letters), and are written in Fortran 90 and later versions (with the first letter capitalized)

C language C language is a general-purpose computer programming language, widely used. The goal of the C language is to provide a programming language that compiles, processes low-level memory, produces a small amount of machine code, and can run without any running environment support in an easy way.

Although the C language provides a lot of low-level processing features, but still maintain a good cross-platform features, a standard specification written in the C language program can be compiled on many computer platforms, and even include some embedded processors (microcontroller or MCU) and supercomputers and other operating platforms.

Pascal Pascal's name is to commemorate the 17th century famous French philosopher and mathematician Blaise Pascal, which was designed and founded by Professor Niklaus Wirth of Switzerland in the late 60. Pascal language grammar rigorous, hierarchical, easy to write programs, readability is strong, is the first structured programming language.

Simula The Norwegian scientist Ole-johan Dahl and Kristen Nygaard officially released the Simula 67 language at the IFIP TC-2 working meeting held in Benzine, a small town on the outskirts of Oslo, Norway, May 20, 1967. Simula 67 is considered to be the earliest object-oriented programming language, which introduces the basic concepts followed by all subsequent object-oriented programming languages: objects, classes, inheritance. After that, the official text of Simula 67 was formed in February 1968.

C + + C + + is an object-oriented programming language developed on the basis of C language, which is widely used; C + + supports a variety of programming paradigms-object-oriented programming, generic programming, and procedural programming. The latest official standard C + + was announced on August 18, 2014. [1] Its wide range of programming, often used in system development, engine development and other applications, is by far the most popular programmers to use one of the most powerful programming language, support class: Class, encapsulation, overloading and other features!

Java Java is an object-oriented programming language that can compose cross-platform applications. Java technology, with its versatility, efficiency, platform portability and security, is widely used in PCs, data centers, game consoles, science supercomputers, mobile phones, and the Internet, while owning the world's largest developer professional community.

Smalltalk Smalltalk is recognized as the second object-oriented programming language in history and the first truly integrated development environment (IDE). Developed by Alan Kay,dan ingalls,ted Kaehler,adele Goldberg equals the early 70 at Xerox PARC. Smalltalk has played a great role in the production of many other programming languages, including: Objective-c,actor, Java, and Ruby. Many software development ideas in the 90 benefited from Smalltalk, such as Design Patterns, Extreme programming (XP) and refactoring.

Perl Perl, a feature-rich computer programming language, runs on more than 100 computer platforms for a wide range of applications, from mainframe to portable devices, from rapid prototyping to massively scalable development.

PythonPython is an object-oriented, interpreted computer programming language, invented by Guido van Rossum in 1989, and the first public release was released in 1991. is purely free software, source code and interpreter CPython follow the GPL (GNU general public License) Agreement [1]. The syntax is simple and clear, and one of the features is to force whitespace (white space) to be indented as a statement.
PHP is a common open source scripting language. The grammar absorbs the C language, Java and Perl features, is conducive to learning, widely used, mainly for the field of web development. PHP's unique syntax mixes C, Java, Perl, and PHP's self-created syntax A scripting language created for simple and fast object-oriented programming (object-oriented program design), developed by the Japanese as (Yukihiro Matsumoto) in the 1990s, complies with the GPL protocol and Ruby License. Eiffel Eiffel language is another "pure" oopl following Smalltalk-80. This language is known by the OOP field of experts Bertrand Meyer and others in the late the 1980s at Ise Corporation (Interactive software Engineering Inc). Developed, its main features are comprehensive static typing, a large number of development tools, support multiple inheritance. Erlang Erlang is a common, concurrency-oriented programming language developed by Cs-lab, a Swedish telecommunications equipment manufacturer, designed to create a programming language and operating environment that can handle large-scale concurrent activities. Erlang was launched in 1987, and after 10 years of development, the open source version was released in 1998. Erlang is an interpreted language that runs on virtual machines, but now also includes a native code compiler developed by the University of Uppsala High Performance Erlang program (HiPE), starting with the r11b-4 version, and Erlang is also beginning to support scripted interpreters. In the programming paradigm, Erlang is a multi-paradigm programming language that covers functional, concurrent, and distributed. The sequential execution of Erlang is a functional programming language for early evaluation, single assignment, and dynamic typing. Lua is a small scripting language. A research group in the Catholic University of Rio de Janeiro, Brazil (Pontifical Catholic University of Rio de Janeiro), by Roberto Ierusalimschy, Waldemar Celes and Luiz Henr Ique de Figueiredo was formed and developed in 1993. It is designed to be embedded in the application, providing flexible extension and customization capabilities for the application. LUA is written in standard C and can be compiled and run on almost all operating systems and platforms. LUA does not provide a powerful library, which is determined by its positioning. So Lua is not suitable as a language for developing standalone applications. Lua has a simultaneous JIT project that provides instant compilation capabilities on a specific platform.
