# checkdigitCalculator
|
|
|
|
This is a calculator written in Go to process a text file of a large list of UPCs calculating their Check Digits.
|
|
|
|
## Instructions
|
|
|
|
### Windows
|
|
#### Create Directory and "Install" Program
|
|
1. Create a directory, that you will remember and is easy to to type, to copy the binary (checkdigitcalc.exe) into.
|
|
2. Copy the binary into that directory.
|
|
|
|
#### Prepare Text File
|
|
1. Open a Text Editor and Paste UPCs (taking care to remove any Alphabet characters).
|
|
2. Save the file with any name you want ending in .txt or .csv in the directory where you put the program. (i.e. upcs.txt)
|
|
|
|
#### Run the Program
|
|
1. Copy the location of the directory from File Explorer
|
|
2. Open cmd.exe or PowerShell
|
|
3. type "cd " (don't forget the space) and press Shift+Insert (or Right Click) and press Enter.
|
|
4. Back in the command line program type checkdigitcalc.exe (I like to type check and then press tab).
|
|
5. The program will ask for the name of the file. Type the name of the text file you created including the extension (.txt or .csv) (i.e. upcs.txt)
|
|
6. When the program finishes, it will exit. Open the answer.txt file that was produced/rewritten by the program. |
