Web Programmning Language

PHP
-- is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. If you are new to PHP and want to get some idea of how it works, try the introductory tutorial.

AppleScript

-- is a scripting language created by Apple Inc. and built into Macintosh operating systems since System 7. The term "AppleScript" may refer to the scripting system itself, or to particular scripts that are written in the AppleScript language.

AppleScript is primarily an inter-application processing system, designed to exchange data between and control other applications in order to automate repetitive tasks.

Datalog 

-- is a query and rule language for deductive databases that syntactically is a subset of Prolog. Its origins date back to the beginning of logic programming, but it became prominent as a separate area around 1977 when Herve Gallaire and Jack Minker organized a workshop on logic and databases. David Maier is credited with coining the term Datalog.

Logic

-- is the formal systematic study of the principles of valid inference and correct reasoning. Logic is used in most intellectual activities, but is studied primarily in the disciplines of philosophy, mathematics, semantics, and computer science.

Bliss
-- is the name of a Windows bitmap image included with Microsoft Windows XP, produced from a photograph of a landscape in Sonoma County, California, southeast of Sonoma Valley near the site of the old Clover Stornetta Inc. Dairy. The image contains rolling green hills and a blue sky with stratocumulus and cirrus clouds. The image is used as the default computer wallpaper for the "Luna" theme of Windows XP.


EXAMPLE OF C++

// my first program in C++ #include <iostream> using namespace std; int main () { cout << "Hello World!"; return 0; }

Hello World!

The first panel (in light blue) shows the source code for our first program. The second one (in light gray) shows the result of the program once compiled and executed. To the left, the grey numbers represent the line numbers - these are not part of the program, and are shown here merely for informational purposes.

The way to edit and compile a program depends on the compiler you are using. Depending on whether it has a Development Interface or not and on its version. Consult the compilers section and the manual or help included with your compiler if you have doubts on how to compile a C++ console program.

The previous program is the typical program that programmer apprentices write for the first time, and its result is the printing on screen of the "Hello World!" sentence. It is one of the simplest programs that can be written in C++, but it already contains the fundamental components that every C++ program has. We are going to look line by line at the code we have just written:
