Concepts and an example of how to create a user library within the C++ programming language.

Concept: user defined specific task functions

Most companies have certain tasks that are unique to their company. Collectively the programming staff may decide to build several functions and organize them into one or more user libraries. Specific task functions are often built using a testing shell program. The sole purpose of the testing shell program is to create the specific task functions and to test them to insure that they are working properly. Think of a clam, its shell surrounds the important part, the pearl. A testing shell program surrounds the specific task function (the important part). Usually the testing shell program will be used to create several functions that will be placed into a user defined library. The process flows as follows:

  1. The testing shell program with the specific task functions is built and thoroughly tested.
  2. A copy of the testing shell source code is saved as the header file that once modified will be placed in the user library. You delete the main part of the program leaving a comments area, any needed include file references and the specific task functions.

  3. Another copy of the testing shell source code is saved as the prototypes file . This is a text file that retains only the prototypes for the functions that were placed into the header file . The functions should be using meaningful identifier names, thus the prototypes should provide adequate information to others on how to call the function with appropriate parameter passing.

  4. Another copy of the testing shell source code is saved as the verify header program . You delete the functions prototypes and definitions then provide an include that points to the header file. This program is compiled and run to make sure the header file is working properly.

A good way to understand the concept is to review the four files described above that have been created by a programmer. We will be using the C++ programming language, however the code is easy to understand and will serve our needs well at explaining the concepts; even if you are not familiar with C++.

Demonstration using c++

Creating a folder or sub-folder for the four files

Depending on your compiler/IDE, you should decide where to download and store source code files for processing. Prudence dictates that you create these folders as needed prior to downloading source code files. A suggested sub-folder for the Bloodshed Dev-C++ 5 compiler/IDE might be named:

  • Monitor_Header

If you have not done so, please create the folder(s) and/or sub-folder(s) as appropriate.

Download the four files

Download and store the following files to your storage device in the appropriate folder. You may need to right click on some of the links and select "Save Target As" in order to download some of the files.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
