program headers

    Each language has its own rules for organizing and formatting programs.

    Most (but not all) programming languages start with a program header of some kind.

Pascal

    The program heading in Pascal is the line that starts with the reserved word program, followed by the identifier giving the name of the program, followed by input and output options inside parenthesis, and ending with a semicolon (;) as a statement separater.

program SimpleProgram (output);

Ada

    “11 Each program unit normally consists of two parts: a specification, containing the information that must be visible to other units, and a body, containing the implementation details, which need not be visible to other units.” —:Ada-Europe’s Ada Reference Manual: Introduction: Language Summary

    “12 This distinction of the specification and body, and the ability to compile units separately, allows a program to be designed, written, and tested as a set of largely independent software components.” —:Ada-Europe’s Ada Reference Manual: Introduction: Language Summary See legal information

Python

    You can designate a Python script by using the she-bang or hash-bang line as the first line of your source code.

    #!/usr/bin/env python

            or

    #!/usr/bin/env python options

    The hash-bang line gives the full path for the Python interpretter.


free music player coding example

    Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).

    Create your own copy from the original source code/ (presented for learning programming).

    Work on this project is very slow because I am homeless. I am available for work if someone can provide an indoor place to work in Costa Mesa, California, electricity, internet connections, a flat raised working surface (such as a table or desk), a sitting device (such as a chair or stool), and a fully functional reasonably modern used computer. I’m already homeless, so you don’t need to pay me (and I understand how much business people hate the minimum wage law). Just give me a chance to work.

    At the time I write this message I am a few days from becoming homeless. That will greatly interfere with my ability to create this project, which can help nearly 20 million U.S. college students and more than 150 million students world-wide. I am looking for 30 rich people or corporations willing to donate $10 a month to my church so that the church can provide a place indoors for me to continue work. If you want to donate, please see help project. Thanks much.

Supporting the entire project:

    If you have a business or organization that can support the entire cost of this project, please contact Pr Ntr Kmt (my church)
