The project comprises of a shopping mall and is developed on the

C++ platform so that the program can be used for account

management and online shopping.

Here you can shop to your heart’s content. Our program allows you

to shop from different stores as it brings you a Daily Market, a

Bookstore and a Gadget shop all under one roof. It even provides

you with the feature of paying your bill online or saving it as a wish

list. It also provides flexible paying option via VISA or COD.

It has a special feature of displaying the previous bills along with

the current bill.

Technical Information

The logic of this program is based on selective delimitation by get

line function in various files. Firstly we extract the categories by

locating the ‘+’ sign in our storage file. Then the pointer is taken

right to that category number by delimiting the pointer’s position

through an iterative structure for the number of lines which equals

to the choice number. For arts and diagrams, ASCII arts has been

implemented from the file.

FUNCTION DESCRIPTION

void blink Delay execution by printing “Loading”(using

delay loop).

void frontpage Print the designed frontpage using file

“mall.txt”.

void display Used to print the categories page of western

gardens by importing form file “catagories.txt”.

void billing centre Store the user transaction details in file

“payment.txt”.

void readdata Extract the product from stored text file as per

user choice and store details in dynamically

allocated file.

-void main Used to switch between different stores and

implement operations accordingly.
