Question

Create a C# Console app Project in Visual Studios

Menu:

Room number	Amenities	Price
111	1 king size bed	$130.00
112,113,114	2 double beds	$145.00
211,212	1 queen size bed	$125.00
213	1 double bed and 1 sofa bed	$170.50

Write a program called HotelReservations that prompts a guest for a room number. Once the room selection is made, display the amenities and price for the room. Allow the guest to continue choosing multiple rooms if desired (displaying the amenities and price for each one selected). When the guest has no more rooms to select, they should type in -99 to stop selection. When the user enters -99, display the total cost of all rooms selected and end the program. If the user enters a room number that does not exist, the program should display “Input error – try again” and ask for another room selection. Use while loops and switch statements to solve this problem. Display all currency values with 2 decimal places.

Example output:

VolState Inn – Hotel Reservation System

Please enter a room number (or -99 to quit): 112 This is a room with 2 double beds priced at $145.00.

Please enter a room number (or -99 to quit): 110 Input error – try again

Please enter a room number (or -99 to quit): 212 This is a room with 1 queen size bed priced at $125.00.

Please enter a room number (or -99 to quit): -99 Total cost of rooms selected is $270.00.

using System;

public class HotelReservations
{
   public static void Main()
   {
       Console.WriteLine("VolState Inn – Hotel Reservation System");
      
       int total = 0;
       int roomNumber;
      
       do // loop while roomNumber != -99
       {
       Console.WriteLine("Please enter a room number (or -99 to quit): ");
       roomNumber = Convert.ToInt32(Console.ReadLine()); // input room Number
       if (roomNumber == -99) // exit condition
       break;
       // switch cases
       switch(roomNumber)
       {
           case 111:Console.WriteLine("This is a room with 1 King bed priced at $130.00.");
                   total = total + 130;
                       break;
          
           case 112:
           case 113:
           case 114:Console.WriteLine("This is a room with 2 double beds priced at $145.00.");
                       total = total + 145;
                       break;
          
          
           case 211:
           case 212:Console.WriteLine("This is a room with 1 queen size bed priced at $125.00.");
                       total = total + 125;
                       break;
          
           case 213: Console.WriteLine("This is a room with 1 double bed and 1 sofa bed priced at $170.00.");
                       total = total + 170;
                       break;
                      
           default: Console.WriteLine("Input error – try again");
                       break;
          
       }
       }while(roomNumber != -99);
      
Console.WriteLine("Total cost of rooms selected is ${0:0.00}",total);// display total cost
   }
