Changing currency from U.S. Dollars to any other currency is necessary and important for individuals and businesses. Following is a program that will do the currency conversions for these businesses or individuals with ease, however, in this paper one can find the behind the scenes programing of such work, which is a bit more detailed than the end user sees.
In this paper, one can find instructions on what the end user will need to enter and in which order to enter such information in order to give accurate data output. This will assist in avoiding errors, in order to avoid the garbage in garbage out cliché from occurring to the end user. To avoid this cliché, there is a piece in the instructions and end user prompts, which will identify obvious errors in the process, before finishing the process, which in turn will minimize incorrect data. This step would prompt the end user to review, confirm and correct any information which may look incorrect to the system.
One can also find in this paper the examples of how each process works in the background to give accurate results. There will be a total of three artifacts and one set of instructions on how end users must enter data. There will be instructions in programing order, but one can also find following these instructions, charts which may make instructions easier to follow, or at least easier to understand.
