Restaurants are evolving and continuously offering a variety of fresh menus and services to attract customers. The survivability of a restaurant depends on its financial management, in which some kind of Restaurant Management System is adopted. For instance, the Point of Sale (POS) system is required to record sales and payments. The Selera Medan restaurant is a new restaurant that offers Indonesian menus as listed in the 'SM_Menu.txt' file. This restaurant is yet to have a POS System. You are required to create a POS system for the restaurant that has the following features: 1) Ability to display the existing menu and price, with the editing options (add/delete menu) 2) Ability to enter the menu and quantity of purchase multiple times, then calculate the total purchase price 3) Ability to save the purchase details in a text file and produce sales reports for one-day and one- month operations. The format of the text file is as follows: Date: 2022-01-01 Transaction time 08:20:45 08:31:02 Total (RM) 150.50 87.80 Accumulated Total (RM) 150.50 238.30 Figure 1: One-day transaction Month: 2022-01 Date 2022-01-01 2022-01-02 Total (RM) 238.30 555.00 Accumulated Total (RM) 238.30 793.30 Figure 2: One-month transaction
