You're developing a Python program for "Tech Trend Electronics," an online electronics store. The store offers three flagship products: SmartWatch Pro, UltraSlim Laptop, and High-Res Camera. Could you outline the logic and structure of a program that provides information about these products, including features, prices, and specifications? Requirements: Display details for each product, such as key features, pricing, and technical specifications. Implement a shopping cart functionality that allows users to add products, specify quantities, and calculate the total cost. Incorporate a discount system where users get a $50 discount on the total cost if they purchase two or more products. Include an optional section for users to select extended warranty options for each product. Output a summary of the user's selected products, quantities, total cost, selected warranty options, and any additional notes after they interact with the shopping cart.
