Question

Create an application for a library and name it FineForOverdueBooks. TheMain() method asks the user to input the number of books checked out and the number of days they are overdue. Pass those values to a method named DisplayFine that displays the library fine, which is 10 cents per book per day for the first seven days a book is overdue, then 20 cents per book per day for each additional day.

The library fine should be displayed in the following format:

The fine for 2 book(s) for 3 day(s) is $0.60

The numbers will vary based on the input.

In order to prepend the $ to currency values, the program will need to use the CultureInfo.GetCultureInfo method. In order to do this, include the statement using System.Globalization; at the top of your program and format the output statements as follows: WriteLine("This is an example: {0}", value.ToString("C", CultureInfo.GetCultureInfo("en-US")));

CODE:

using System;

using static System.Console;

using System.Globalization;

public class FineForOverdueBooks

{

   public static void Main()

   {

    // Write your main here.

   }

   public static void DisplayFine(int books, int days)

   {

    // Write your DisplayFine method here.

   }

}

class FineForOverdueBooks
{
    static void Main()
    {
        Console.WriteLine("Enter number of books:");
        int b = Convert.ToInt32(Console.ReadLine());
        Console.WriteLine("Enter number of days:");
        int d = Convert.ToInt32(Console.ReadLine());
        DisplayFine(b,d);
    }
    
   public static void DisplayFine(int books, int days){
        int amt=0;
        if(days<=7){
          amt=books*10*days;
        }
        else if(days>7){
          amt=books*10*7+books*20*(days-7);
         }
      WriteLine("Amount Due: {0}", amt.ToString("C", CultureInfo.GetCultureInfo("en-US")));
    }

}
