Instructions

Replit Folder: companydb$-$cpp

This will be an object oriented C$++$ program with the following behavior:

At the program's start, it will prompt for the name of a company.

The program will attempt to load the company's data from the file "name.dat". For example, if you enter "acme" it will try to load from "acme.dat". If the file does not exist, the program will create a blank one.

The program will then present a menu that lets the user do the following:

View$/$Add Employees

View$/$Add Sales and Customers

Exit

Upon program exit, it will save the contents of the company database to the file specified above.

Design

Submission

Your submission will be graded directly from your private replit. The commands I will run to grade your program are:

cd companydb$-$cpp

make

grade $./$companydb

You should try this yourself! This will generate a file called "GRADE.TXT$".$ If this file shows all successful runs, you will receive full marks. I will be grading your programs using this automated grading system, so please be careful to match my input and output as closely as you can! Your grade will be based on the total number of tests your code completes as well as the quality of your code.
