CODE MUST BE IN C#(CSHARP)

Congratulations! You've been contracted by an international hotel to build a new application to manage functions within the hotel. While this app will eventual service all of the hotel's needs, this project will focus on 2 primary functions - currency exchange and restaurant point of sale. Even within those systems, phase I will focus on building only the basic features. Menu: - The app should provide a user menu with 3 options. - Convert currencies - The system must support converting to and from US dollars. - The system must prompt the user to determine from and to currency type. Supported currencies and exchange rates are on the next slide - The system prompts the user for the corresponding currency amounts. - The system must provide the user with the exchange amount. - + Supported Currencies: - Restaurant POS - The system must prompt the user for food total. - The system must prompt the user for alcohol total. - The system must add 9% tax to the total bill. - The system must add an 18% tip on non-alcohol related items. - The system must provide the user with the total amount due. - The system must prompt the user for the amount paid - The system should provide an error if the amount paid is less than the amount owed. - The system should display the change due. - Exit - The menu should do error checking and inform the user if they did not make a valid selection and then show the menu again. - Each menu item must have a test log, design doc, and source code submitted - The two test logs and design docs should be in a single document
