The program should display a list of items and the location in the store. The user must be able to enter the items and location in the store. You will use a class for the items. For this assignment, you will implement creating the list, adding elements, removing elements, and displaying the shopping list. There is other information.

Some people shop on a budget so they need the price and the sale price. Use an array or vector to hold the list of items. The display should show the items by zone or location within the store. (Display the output by location.)

Summary: 1. Implement a shopping list program that asks the user for the name of the product – you need to have class item. Use an array or vector to hold the list of items. 2. The user also needs to enter the location (it can be isle number that will be translated into product category (for example poultry, baby items, hygiene, etc). You can be creative here. Use an array or vector to hold the list of items. 3. The user also needs to add regular price and sales price, if the product is on sale. 4. The user should be able to add as many products as they want. 5. The user should be able to remove item from the list (Use menu). 6. The user should be able to display shopping list. The display should show the items by zone or location within the store. Also display should show the regular and sales price of the item as well as compute the total bill and total savings.

Implementing a comprehensive shopping list application involves integrating object-oriented programming principles with efficient data structures to handle dynamic user interactions. The core objectives include allowing users to input items with associated details, categorize them based on store locations, and perform operations such as adding, removing, and displaying items. Additionally, the program calculates total costs and savings, offering practical utility for budget-conscious shoppers.

At the heart of this application lies the definition of an 'Item' class, encapsulating properties such as item name, location, regular price, and sale price. This class serves as the blueprint for creating item objects that can be stored within an array or vector. Using vectors (in C++) or array lists (in Java) is preferable because of their dynamic resizing capabilities, which accommodate an unpredictable number of shopping items.

The user interaction is managed through a menu-driven interface, providing options to add items, remove items, display the shopping list, and exit the program. When adding items, the user inputs the product name, category or location (such as aisle number, which can be mapped to categories like poultry, hygiene, or beverages), and the pricing details. If an item is on sale, both the regular and sale prices must be recorded. Removing items typically involves selecting from a numbered list, which the program then deletes from the collection.

A key feature of this system is the display functionality, which groups items by their location within the store. This enhances user understanding of where items are situated and facilitates efficient shopping. The display also shows each item's name, regular price, sale price if applicable, and calculates cumulative totals — the overall bill, encompassing the sum of all item prices, and total savings, representing the difference between regular and sale prices across all items.

Implementing these features requires careful management of data, clear user prompts, and accurate calculations. For example, summing prices necessitates iterative addition, considering only the sale price if an item is on sale, or the regular price otherwise. Additionally, categorizing items based on input location involves either having predefined categories or allowing flexible assignment. Proper validation and error handling should be incorporated to ensure robustness.

In conclusion, designing a shopping list program as described offers valuable experience in object-oriented programming, dynamic data structures, user interaction, and data processing — all essential skills in software development. By organizing items into classes, managing collections efficiently, and providing user-friendly operations and outputs, such a program can be both educational and practically useful.
