The task entails developing a comprehensive shopping list program in C++, emphasizing object-oriented principles. The program should allow users to manage a store inventory and a shopping cart through a menu-driven interface. Fundamental functionalities include creating and emptying the store list, adding items with detailed attributes, removing specific items, displaying items grouped by store location, and handling a shopping cart with functionality to add, display, and delete items. The design mandates the use of classes, particularly an item class to model product details, and a storeManager class to oversee inventory and cart operations, leveraging either vector or array data structures for storage.

Each item must contain information such as name, location within the store, regular price, and sale price if applicable. Users should be able to input new items, specifying these details, and the system should facilitate their management and display, sorted or grouped by their store location. The store's display functionality must present a clear view of the inventory, showing product details and prices, and enabling the user to interactively select items for purchase or removal.

The shopping cart feature will compile selected items, calculate total costs, and determine total savings, providing a detailed purchase summary. Price handling involves calculating potential savings when sale prices are available, thereby helping users shop within their budgets. The program should be robust, handling invalid inputs gracefully, and providing a user-friendly interface through clear prompts and outputs.

Implementing a shopping list management system requires a well-structured approach using C++ classes and Standard Template Library (STL) containers such as vector. The primary class, item, encapsulates product attributes, including name, location, regular price, and sale price. The storeManager class orchestrates the inventory and shopping cart, providing methods to create an empty store, add or remove items, display inventory and cart, and process shopping transactions.

The item class serves as a blueprint for each product, ensuring consistent handling of product data. Its design includes data members and possibly member functions for data access, although for simplicity, public members can suffice given the program's scope. The storeManager class maintains two vectors: one for store inventory and another for the shopping cart, enabling dynamic addition, removal, and iteration over items.

The core functionalities involve creating a new store with createStore(), adding items with addItem() by prompting user input for each attribute, and removing items via an index selected by the user. The removal process involves verifying the index validity and updating the vector accordingly. Display functions such as displayList() and displayCart() provide formatted output, possibly sorted or grouped by location or category.

The implementation also includes mechanisms for users to add items to their shopping cart, view the total cost, including handling sale prices, and calculate potential savings by comparing regular and sale prices. These features assist users in shopping within their budget constraints while providing them with detailed information about their selected products.

From an operational perspective, the program uses a menu-loop, capturing user selections with input validation, and invoking corresponding methods in the storeManager class. The interface is designed for clarity, guiding the user through options with prompts and formatted outputs. Upon choosing to quit, the program terminates gracefully, displaying a farewell message.

This system embodies good practice by compartmentalizing functionality, using dynamic data structures, and facilitating user interaction with robust input handling. It encapsulates typical store management activities in a console-based application suitable for learning and practical application in C++ programming.
