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.
