Generational list of programming languages Here, a genealogy of programming languages is shown. Languages are categorized under the ancestor language with the strongest influence. Of course, any such categorization has a large arbitrary element, since programming languages often incorporate major ideas from multiple sources.

Category:Programming Languages For the programming language, see Category:Programming Language. A programming language is a symbolic representation of a specification for computer behavior. A side-by-side comparison of many of the languages on Rosetta Code can be seen here. These are the programming languages that are mentioned throughout Rosetta Code. Note Because this category is used for automated administration, it should contain only categories that represent individual languages, not groups of languages. Subcategories This category has the following 200 subcategories, out of 921 total.

Interpreter (computing) parse the source code and perform its behavior directlytranslate source code into some efficient intermediate representation and immediately execute thisexplicitly execute stored precompiled code[1] made by a compiler which is part of the interpreter system While interpretation and compilation are the two main means by which programming languages are implemented, they are not mutually exclusive, as most interpreting systems also perform some translation work, just like compilers. The terms "interpreted language" or "compiled language" signify that the canonical implementation of that language is an interpreter or a compiler, respectively. An illustration of the linking process. At the stage of compilation, in fact compilers act as interpreters and patch together such binary executables from an object code library defining which binary code sequence is named which command name. An interpreted program can be distributed as source code.
acmeism/RosettaCodeData: RosettaCode Data Project Compiler A diagram of the operation of a typical multi-language, multi-target compiler A compiler is a computer program (or set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language, often having a binary form known as object code).[1] The most common reason for wanting to transform source code is to create an executable program. Program faults caused by incorrect compiler behavior can be very difficult to track down and work around; therefore, compiler implementors invest significant effort to ensure compiler correctness. The term compiler-compiler is sometimes used to refer to a parser generator, a tool often used to help create the lexer and parser. History[edit] Software for early computers was primarily written in assembly language. Towards the end of the 1950s, machine-independent programming languages were first proposed.

When and how to use an assembler. Assembly programming basics. The basics of programming in assembly, the design of the processor, registers, memory, instruction, and use of assembly language within C++ and Delphi. 1. Introduction to assembly Assembly language, a low-level programming language which allows you to use all the features of a computer processor is nowadays somewhat forgotten by “modern” developers. The main reason for this is that writing in assembly is not the simplest of tasks, and is very time-consuming (testing code, finding bugs etc.). However, in some situations assembly may be an ideal solution. Despite incredible advancements in compilers in recent years, algorithms such as Blowfish, Rijndael, Idea written in assembly and “manually” optimised show significant speed advantages over their counterparts written e.g. in C++ and compiled at the maximum optimisation level. In addition to cryptography, assembly is also often used by game developers. So let's get started. 2. 2.1. What is a register? 2.2. 2.3. 2.4. 3. 3.1. 3.2. 3.3. 4. 5.
Algorithm Flow chart of an algorithm (Euclid's algorithm) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B. The algorithm proceeds by successive subtractions in two loops: IF the test B ≥ A yields "yes" (or true) (more accurately the numberb in location B is greater than or equal to the numbera in location A) THEN, the algorithm specifies B ← B − A (meaning the number b − a replaces the old b). Similarly, IF A > B, THEN A ← A − B. In mathematics and computer science, an algorithm ( i/ˈælɡərɪðəm/ AL-gə-ri-dhəm) is a step-by-step procedure for calculations. Informal definition[edit] While there is no generally accepted formal definition of "algorithm," an informal definition could be "a set of rules that precisely defines a sequence of operations Boolos & Jeffrey (1974, 1999) offer an informal meaning of the word in the following quotation: The term "enumerably infinite" means "countable using integers perhaps extending to infinity."
Web Services Introduzione: i web services Nel 1998 seguendo la strada tracciata da XML prende forma il concetto di Web Services. Ma cosa è un web service? Un Web Service è una applicazione modulare descritta, pubblicata, individuata ed utilizzata attraverso il web. Un Web Service può essere sfruttato contemporaneamente per più operazioni, essendo condiviso in rete e disponibile a tutti. Web Services: il concetto L'idea fondamentale che sta alla base dei Web services è l'integrazione come servizio. Nella sua essenza il concetto dei Web services è un diverso approccio alla distributed computing. Caratteristiche Come comportamenti dinamici i Web services includono : Funzionalità di self-description Pubblicazione di service description Localizzazione di funzionalità richieste Domanda di dati richiesti Scambio di dati con altri Web services Cosa possono fare i Web services I Web services possono potenzialmente unire sistemi eterogenei di qualsiasi tipo – inclusi sistemi legacy.
Flowchart A simple flowchart representing a process for dealing with a non-functioning lamp. A flowchart is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. This diagrammatic representation illustrates a solution to a given problem. Overview[edit] Flowcharts are used in designing and documenting complex processes or programs. a processing step, usually called activity, and denoted as a rectangular boxa decision, usually denoted as a diamond. A flowchart is described as "cross-functional" when the page is divided into different swimlanes describing the control of different organizational units. Flowcharts depict certain aspects of processes and they are usually complemented by other types of diagram. Nassi-Shneiderman diagrams and Drakon-charts are an alternative notation for process flow.
