  C programming language
C is a programming language, designed by Dennis Ritchie during the early 1970s, for writing the UNIX operating system.
C is a high level language, meaning that the source code of a program can be written without detailed knowledge of the computer's CPU type.
By 1973, the C language had became powerful enough that most of the kernel of the Unix operating system was reimplemented in C. This was the first time that the kernel of an operating system had been implemented in a high level language.

 Wikinfo | S2
S2 is an object-oriented programming language developed by Brad Fitzpatrick, Martin Atkins and others for the picture-hosting website code FotoBilder as well as the online journalling service LiveJournal in order to allow users full control over the appearance of their pages.
S2 source code is compiled into Perl, which the webserver can then execute directly for individual web page requests.
The S2 language introduces a concept of properties — these are variables that are not specific to a particular object or class, but to a layer.

 The Icon Programming Language
The Icon programming language [4] was developed to integrate and generalize SNOBOL4's facilities, as well as to provide a familiar syntax resembling Pascal and C. More recently, Icon has added graphics facilities to support the visual presentation of data and interactive user interfaces [5].
Icon is a high-level programming language; its features are cast close to the problem domain instead of the hardware of the computers on which it runs.
Programming languages, most of which were designed and implemented before graphics facilities were widely available, have lagged.

 www.cybermight.com programming - Programming languages
Since programming languages are artificial languages, they require a high degree of discipline to accurately specify which operations are desired.
Programming languages are not error tolerant; however, the burden of recognizing and using the special vocabulary is reduced by help messages generated by the programming language implementation.
There are a few languages which offer a high degree of freedom in allowing self-modification in which a program re-writes parts of itself to handle new cases.

 S2 (programming language) - Wikipedia, the free encyclopedia
S2 (Style System 2) is an object-oriented programming language developed in the late 1990s by Brad Fitzpatrick, Martin "Mart" Atkins, and others for the online journalling service LiveJournal in order to allow users full control over the appearance of their pages.
The S2 system is, at its heart, completely general and can be used for almost any web application; however there exists no documentation for the implementation of S2 within other applications, which ties it relatively closely to LiveJournal.
S2 incorporates the idea of providing documentation for a class, method, function or property directly within the source code, separate (machine-distinguishable) from conventional comments.

 A Very Quick Comparison of Popular Languages for Teaching Computer Programming
Java and C are the most commonly used languages in the department, and for many subjects this is appropriate, but not (I believe) for absolute beginners.
C is a major and very important language, and all programmers should have significant exposure to it.
Java is a useful language for cross-platform GUI development, is a robust platform for OO development, and has an extensive and highly evolved set of class libraries.

 Programming Languages Proposal for Curriculum 2001
Language translation understood conceptually as an implementation on a virtual machine, followed by a sequence of translations to simpler core languages through a hierarchy of virtual computers.
The student should be made aware of how the syntax of a programming language is formally specified, thus enabling the programming language designer to communicate the language syntax to the users and language implementers.
With the advent of the first truly popular garbage collected language, Java, it is increasingly important for the student to understand the implementation issues and program correctness issues (explicit vs. automatic allocation/deallocation) involved in choosing a language based on a particular memory allocation/deallocation model.

 Dynamic Programming Algorithm, Edit Distance
The longest common subsequence (LCS) of two sequences, s1 and s2, is a subsequence of both s1 and of s2 of maximum possible length.
One approach is for the program (on machine-1) to keep a "picture" of what the screen currently is (on machine-2) and another picture of what it should become.
If your programming language does not support 2-dimensional arrays, and requires arrays or strings to indexed from zero upwards, some home-grown address translation will be needed to program the DPA defined above.

 The Sather Language: Efficient, Interactive, Object-Oriented Programming
One way of placing it in the "space of languages" is to say that it aims to be as efficient as C, C++, or Fortran, as elegant and safe as Eiffel or CLU, and to support interactive programming and higher-order functions as well as Common Lisp, Scheme, or Smalltalk.
In languages which do not separate abstract types from particular implementations, you are either forced to make all descendants implement routines which don't make sense for them or to leave out functionality in parent classes.
Because the compiler uses C as an intermediate language, the quality of the executable code depends on the match of the C code templates used by the Sather compiler to the optimizations employed by the C compiler.

 Ruby—A Diamond of a Programming Language?
This language came to my attention at a Java conference last spring, where gentlemen like Bruce Tate (author of Bitter Java and Better, Faster, Lighter Java), Dave Thomas (Pragmatic Programmer: From Journeyman to Master), and others were all talking about Ruby and telling many of us in the audience it deserved a look.
After all, the programming language wars in the '80s and '90s culminated in the conclusion that there are essentially two camps: the Java world and the development languages that Microsoft supported on.NET.
Without getting into the religious arguments that have occurred in programming language research arenas, let's just say that multiple inheritance can be a very powerful feature, but increases complexity and ambiguity in a language and is not incorporated in many object-oriented languages.

 How programming languages differ: a case study of SPL, Pascal, and C   (Site not responding. Last check: 2007-11-07)
However, it may be wise for you to have manuals for these three languages -- either their HP3000 implementations or general standards -- at hand, in case some of the examples should prove too arcane.
SPL can be said to "support" something only because there is only one SPL compiler that we're talking about.
Similarly, if your language allows functions to return records and arrays as well as scalars, you can easily change the type of your, say, disc addresses from a 2-word double integer to a 10-word array of integers.

 ITworld.com - Crossing the language barrier
Once we know a programming language, we identify ourselves by it -- we're "a C++ programmer," "a Delphi developer," etc. One explanation for this tendency to affiliate is that old barrier to change that naturally exists between programming languages: familiarity.
I prefer to think of each programming language as a specialized tool -- and I recognize that a hammer specialist does not make a good carpenter.
Because the languages implement identity in different ways, developers must be careful when commuting from one to the other.

 RIGAL PROGRAMMING SYSTEM LANGUAGE DESCRIPTION
Programming language RIGAL is intended to be a tool for parsing (context checking, diagnosing and neutralization of errors included), for code optimization, code generation, static analysis of programs, as well as for the programming of preprocessors and convertors.
The main program text must be at the beginning of the RIGAL program text, but the text of the rules is written afterwards.
Patterns of the rule #A_PROGRAM and of the rules subordinate to it, actually, coincide with patterns of the rule #PROGRAM and with the associated rules that describe context free grammar of the TOYLAN language.

 12.3 Programming in Delphi/Kylix and HLA   (Site not responding. Last check: 2007-11-07)
Given the rich set of language features that Delphi supports, it should come as no surprise that the interface between Delphi's Object Pascal language and assembly language is somewhat complex.
The basic unit of interface between a Delphi program and assembly code is the procedure or function.
The following program is a modification of the previous program in this section that uses the register calling convention rather than the pascal calling convention.

 An Overview of the Icon Programming Language; Version 9
Icon is a high-level programming language with extensive facilities for processing strings and structures.
Strings, lists, and other structures are created during program execution and their size does not need to be known when a program is written.
Most programming languages treat this situation by selecting one of the positions, such as the first, as the result of the expression.

 Godiva - a Very-High Level Dialect of Java   (Site not responding. Last check: 2007-11-07)
Godiva is a high-level general-purpose programming language descended from Java, and hence from C. While their low-level built-in operator sets make Java and C best-suited for systems programming, Godiva has higher-level built-in facilities that orient it more towards applications programming.
The decision to omit operator overloading from the language, although arguably the right thing to do, unfortunately precludes Java from offering even the limited means that C++ provides to facilitate concise notations for such features by means of class libraries.
Of these languages, C* and Dataparallel C are of particular interest since they describe features similar to Godiva's aggregate operators in languages that use C syntax as a base, as to Java and Godiva [CPG] [Hat91].

The generated program could be modified or extended, or an application could be written from scratch in Key.
The Programming Environment included a cut-down version of the Macintosh Programmer's Workbench and a debugger, making it possible to set breakpoints, step through code and examine the state of objects in a running application.
Also, Key has been modified extensively to suit the needs of multimedia programming, where it is frequently the case that there will be only one object of each type, or that each object will differ only by the addition of a method or two.

 Rick Byers : Disruptive Programming Language Technologies
"Disruptive Programming Language Technologies" (video, slides) is one of my favorite talks on the future of programming languages.
I’m ashamed to say that it wasn't that long ago that I thought managed languages like Java and VB were "toy" languages that no real serious programmer would choose to use.
For the past few decades, programming language design and implementation research has concentrated heavily in a few notable areas: type theory, functional programming, object-oriented programming, and, of course, optimization techniques.

Some of the perceived shortcomings of C have been addressed by newer programming languages derived from C. The
By 1973, the C language had became powerful enough that most of the kernel of the Unix operating system was reimplemented in C, perhaps following the examples of the Multics system (implemented in PL/I), Tripos (implemented in BCPL), and perhaps others.
(In fact, Normative Amendment 1created a new version of the C language in 1995, but this version is rarely acknowledged.) However, the standard underwent revision in the late 1990s, leading to ISO 9899:1999, which was published in 1999.

 D Programming Language - D Strings vs C++ Strings
Why have strings built-in to the core language of D rather than entirely in a library as in C++ Strings?
In D, array bounds checking is on by default and it can be turned off with a compiler switch after the program is debugged.
The input file alice30.txt is the text of "Alice in Wonderland." The D compiler, dmd, and the C++ compiler, dmc, share the same optimizer and code generator, which provides a more apples to apples comparison of the efficiency of the semantics of the languages rather than the optimization and code generator sophistication.
