Examples of programming languages

Here is a list non-exhaustive of programming languages :

Assembler

An assembler is a program that takes basic computer instructions and converts them into a pattern of bits that the computer's processor can use to perform its basic operations.
In the earliest computers, programmers actually wrote programs in machine code, but assembler languages or instruction sets were soon developed to speed up programming. Today, assembler programming is used only where very efficient control over processor operations is needed. It requires knowledge of a particular computer's instruction set, however. Historically, most programs have been written in "higher-level" languages such as
C. These languages are easier to learn and faster to write programs with than assembler language.


C

C is a structured, procedural programming language that has been widely used both for operating systems and applications and that has had a wide following in the academic community. Many versions of UNIX-based operating systems are written in C. With the increasing popularity of object-oriented programming, C is being rapidly replaced as "the" programming language by C++, a superset of the C language that uses an entirely different set of programming concepts.


C++

C++ is an object-oriented programming language that is now generally viewed as the best language for creating large-scale application programs. C++ is a superset of the C language.


HTML (Hypertext Markup Language)

HTML is the set of "markup" symbols or codes inserted in a file intended for display on a World Wide Web browser. The markup tells the Web browser how to display a Web page's words and images for the user.
HTML is defined in practice both by Netscape and Microsoft as they add changes to their Web browsers and more officially for the industry by the World Wide Web Consortium (W3C). A new version of HTML called HTML 4 has recently been officially recommended by W3C, making this level an effective standard.


JavaScript

JavaScript is an interpreted programming or script language from Netscape. In general, script languages are easier and faster to code in than the more structured and compiled languages such as C and C++ and are ideal for programs of limited capability or that can reuse and tie together existing compiled programs.
JavaScript is used in Web site development to do such things as:
Automatically change a formatted date on a Web page
Cause a linked-to page to appear in a popup window
Cause text or a graphic image to change during a mouse rollover
JavaScript uses some of the same ideas found in Java, the compiled object-oriented language derived from C++. JavaScript code can be imbedded in
HTML pages and interpreted by the Web browser (or client).
