PROGRAM OUTPUT: BANK ACCOUNT DATABASE REPORT FILE

When the user chooses to write a report, a report file shall be written.

The default report file name shall be: BankAcct.Rpt

The program shall give the user the choice of picking a different name for the report file.

If the user chooses to do so, the user shall be prompted to enter the alternate name of the report file.

The report file shall include the same information as the bank account database output file, but it shall be formatted for human viewing, as a table.

The #include file <iomanip> shall be used for this purpose.

GENERAL PROJECT REQUIREMENTS

Programs submitted as part of a project must have an executable built on the Linux server.

Programs submitted as part of a project must satisfy the requirements of the project.

The student must present the project to the class, discussing the project’s requirements and how the program sat-isfies them, giving sample runs for the program, walking through the source codes for the program, discussing the project’s makefile, discussing the program’s shortcomings and known bugs.

SUBMISSION REQUIREMENTS

Submit a “tgz” file named proj1.tgz that contains the entire project: executable, source files, makefile, and data files.

Make sure all your files are in your: Proj1 directory.

Use FileZilla to copy your “.tgz” file from the Linux server over to your Windows machine.

Upload the “tgz” file to Canvas.

Submission verification is possible because you are allowed to download files from Canvas.

You should test your submission by performing the following procedure:

1. Download your “tgz” file from the Canvas drop box.

2. Unzip your “tgz” file (extract its contents).

3. Transfer the file(s) to the server.

4. Be sure to do this in a different “test” directory, so you don’t overwrite previous work.

5. Run the resulting program.
