This is a group assignment. In this assignment you will create a Supermarket Billing System

that allows a user to do the following:

Create a member account by supplying a user id and password.

Login using their id and password.

Quit the program.

Now if login was successful the user will be able to do the following $($you can add in other functions

as well$)$:

Display Menu with $3$ categories such as$,$ canned food, vegetables and fruits and etc.

There are minimum of $4$ items in each of the category. Example : if the user choose category

"vegetable", your program should display $4$ items such as cabbage, carrot, beet root, long

bean and etc.

Add the items to the cart

Calculate the sub total for each item purchased.

Generate the receipt and make payment.

Quit the program.

The final program should include the following features:

File Handling: Use file storage to maintain persistent data on items, stock levels, order,

login credential and etc.

Input Validation: Ensure that all inputs, such as item quantities and prices, are valid.

Real$-$time Updates: Update product quantities immediately after an order is processed or

stock is replenished.

Menu$-$driven Interface: Provide a user$-$friendly interface with options for the menu and

functions.

Part $1$: Analvsis

The objective of this part is to study and gather all the information about the current system running

in the company. Here is the sample information that you can gather and document for this part:

$1\mathrm{.}1$ Literature Review

Company and business background $($in brief$)$

Explain the system in general and how it is supposed to work in terms of the type of

operations.

Description of the working of the current system based on the company $/$ business you

choose $($explaining from input $-$ type of data capture, process $-$ any formulas involve, and

output $-$ type of information produce$)$

Capture sample interface of the system $($from Internet$)-$ if available

$1\mathrm{.}2$ sample document

Get a sample document from the company such as sales report $/$ billing report. $($attach into

the report$)$

Provide a brief description of the document.

Part $2$: Design

The objective of this part is to document your idea about the design of your proposed system $($and

based on the sample company$).$ You are required to divide the system into $3$ modules, such as login

module, data capturing module, or output module separately.

$2\mathrm{.}1$ Description of the system: explain the following using PAC Chart and System Flowchart

Input $-$ type of data capture

Process $-$ type of programming methods used, formulas need

Output $-$ type of output produce

Explain the types of modules in your system $($at least $3$ modules$/$functions$)$

$2\mathrm{.}2$ Storyboard

Draft of sample design of your proposed system $($with sample data and output$/$information$)$

PROGRAM SPECIFICATION:

You are required to create a C$++$ program for the system that you have analyzed and designed.

Each group is required to have the based program and task distribution need to be defined. Each

of the member in the group is required to have a separate program to demonstrate your own part

of coding with the methods used $($Function$,$ Array, Structures, or File Processing$).$ Then, compile

the program by merging the $4$ individual programs into $1$ final program. Lastly, prepare the final

report at the end of the assignment.

PART $1$: Coding

You need to use various types of programming methods to solve the above problem

$($control structures, functions, arrays and structures, File Processing$)$

In order to store the data in both systems, you should use array or structures concepts.

All input$/$output operations should be done in the function main and all

calculations$/$processing in whatever other functions seem appropriate.

You need to create a modular program that have at least $4$ functions, and examples as the

following:

Heading $($instructions$/$message$)$

Login system

Type of operations

The program will be marked based on the following criteria:

Completeness of requirements

Good program practices

Readiness

Indentation

comments

Meaningfulness in the input$/$output format

Design$/$logic flow of the program

Efficiency in terms of methods used

Flexibility of the program

Free of bugs

PART $2$: REPORT REQUIREMENTS:

Each group is required to prepare the report based on the following content arrangement:

Cover Page

Marking Scheme
