Total Price Calculation: The total price of items in the cart is calculated, helping users keep track of their expenditure. Checkout: A simple checkout process to finalize the purchase of items in the cart. User Interface:

Command-line interface with intuitive prompts and menu options for ease of use. Error handling for invalid inputs and operations. Technical Details: Data Structures:

Doubly Linked List: Each node contains pointers to the previous and next nodes, enabling traversal in both directions. Item Node Structure: Contains fields for item name, quantity, and price. Functions:

Add Item: Inserts a new item node at the end of the list. Remove Item: Deletes a specified item node from the list. Display Items: Traverses and displays all items in the list. Move Item: Transfers an item node from the wishlist to the shopping cart. Calculate Total: Computes the total cost of items in the cart.
