Programming paradigm

Programming paradigm
A programming paradigm is a fundamental style of computer programming, a way of building the structure and elements of computer programs. Capablities and styles of various programming languages are defined by their supported programming paradigms; some programming languages are designed to follow only one paradigm, while others support multiple paradigms. There are six main programming paradigms: imperative, declarative, functional, object-oriented, logic and symbolic programming.[1][2][3] Overview[edit] Overview of the various programming paradigms[4]:5 In object-oriented programming, programmers can think of a program as a collection of interacting objects, while in functional programming a program can be thought of as a sequence of stateless function evaluations. Programming paradigms can also be compared with programming models which are abstractions of computer systems. History[edit] Machine code[edit] Procedural languages[edit] All these languages follow the procedural paradigm.

Event-driven programming Event handlers[edit] A trivial event handler[edit] Because the code for checking for events and the main loop do not depend on the application, many programming frameworks take care of their implementation and expect the user to provide only the code for the event handlers. How to use Twitter Bootstrap to Create a Responsive Website Design "Welcome to the responsive web!" In the last year or so this term has been thrown around everywhere, so often that even a lot of my clients are asking for a responsive design from the get go. This, to me, is really interesting because they never asked for a mobile or tablet version back in the day. One would argue that mobile wasn't so mainstream and everybody was trying to imitate the IOS interface on the web, and I agree, it was bad, but that's not the only reason why clients are asking for responsive!?

HomePage - Kwiki History of Programming Languages Wiki Among our friends, authors, and editors, there is a high level of historical knowledge and personal experience of the events in the History of Programming Languages poster. We hope to inspire and capture your comments and discussion here in in this wiki. Just click the EDIT button below to post your comments on this page. REXX Rexx is supplied with VM/SP on up, TSO/E Version 2 on up, OS/2 (1.3 on up), AmigaOS Version 2 on up, PC DOS (7.0 or 2000), and Windows NT 4.0 (Resource Kit: Regina). REXX scripts for OS/2 share the filename extension .cmd with other scripting languages, and the first line of the script specifies the interpreter to be used. A Rexx script or command is sometimes referred to as an EXEC in a nod to Rexx's role as a replacement for the older EXEC command language on CP/CMS and VM/370 and EXEC 2 command language on VM/SP. Features[edit]

Logic programming Logic programming is a programming paradigm based on formal logic. Programs written in a logical programming language are sets of logical sentences, expressing facts and rules about some problem domain. Together with an inference algorithm, they form a program. Major logic programming languages include Prolog and Datalog. Object-oriented programming Overview[edit] Rather than structure programs as code and data, an object-oriented system integrates the two using the concept of an "object". An object has state (data) and behavior (code). Objects correspond to things found in the real world. Terminology, Syntax, & Introduction - A Beginner's Guide to HTML Before beginning our journey to learn HTML and CSS it is important to understand the differences between the two languages, their syntax, and some common terminology. As an overview, HTML is a hyper text markup language created to give content structure and meaning. CSS, also known as cascading style sheets, is a presentation language created to give content style and appearance.

The History of Programming Languages For 50 years, computer programmers have been writing code. New technologies continue to emerge, develop, and mature at a rapid pace. Now there are more than 2,500 documented programming languages! The History of C++ Programming Language - Authentic Society Notes on the difference between C an C++ You may hear from time to time that the C++ programming language is a superset of the C language. In C++, you can do almost everything you can do in C, with the exception of just a small number of things that may be considered specification details. Nonetheless, C and C++ are two different languages. One of the important points I'd like to make is that it is not desired to write C programs in a C++ compiler, although it is possible.

Prolog Prolog is a general purpose logic programming language associated with artificial intelligence and computational linguistics.[1][2][3] Prolog has its roots in first-order logic, a formal logic, and unlike many other programming languages, Prolog is declarative: the program logic is expressed in terms of relations, represented as facts and rules. A computation is initiated by running a query over these relations.[4] The language was first conceived by a group around Alain Colmerauer in Marseille, France, in the early 1970s and the first Prolog system was developed in 1972 by Colmerauer with Philippe Roussel.[5][6] Prolog was one of the first logic programming languages,[7] and remains the most popular among such languages today, with many free and commercial implementations available. Prolog is well-suited for specific tasks that benefit from rule-based logical queries such as databases searching, voice control systems, and template filling.

Event loop When the event loop forms the central control flow construct of a program, as it often does, it may be termed the main loop or main event loop. This title is appropriate because such an event loop is at the highest level of control within the program. Message passing[edit] Introduction — Problem Solving with Algorithms and Data Structures We stated earlier that Python is an object-oriented programming language. So far, we have used a number of built-in classes to show examples of data and control structures. One of the most powerful features in an object-oriented programming language is the ability to allow a programmer (problem solver) to create new classes that model data that is needed to solve the problem. Remember that we use abstract data types to provide the logical description of what a data object looks like (its state) and what it can do (its methods).

List of programming languages The aim of this list of programming languages is to include all notable programming languages in existence, both those in current use and historical ones, in alphabetical order, except for dialects of BASIC and esoteric programming languages. Note: Dialects of BASIC have been moved to the separate List of BASIC dialects. Note: This page does not list esoteric programming languages. A[edit] B[edit]
