BILL generator @ console

Hi everyone

Create a console program that allows a user to enter a list of prices and generate a receipt.

The receipt must show the list of prices, the subtotal, tax amount @9%, and a grand total. All numbers must be aligned in a single column with the summary fields labeled. Be sure to include a heading of "Bob's Supermarket" and footer thanking the customer on the receipt. ALL WORK MUST BE DONE IN FUNCTIONS

Cheers ty

Try this:

using System;

using System.Collections.Generic;

class Program

{

static void Main()

{

List prices = GetPrices();

ShowReceipt(prices);

Console.ReadKey();

}

static List GetPrices()

{

List prices = new List();

Console.WriteLine("Enter prices or a number <= 0 to finish\n");

decimal price;

bool isValid;

int count = 0;

while(true)

{

count++;

Console.Write(" Price {0,2} : ", count);

isValid = decimal.TryParse(Console.ReadLine(), out price);

if (price > 0m) prices.Add(price);

if (isValid && price <= 0m) break;

if(!isValid)

{

Console.WriteLine(" Not a valid price. Please re-enter");

count--;

}

return prices;

}

static void ShowReceipt(List prices)

{

Console.Clear();

Console.WriteLine(" Bob's Supermarket");

Console.WriteLine(" -----------------");

Console.WriteLine(" $");

decimal subtotal = 0m;

foreach(decimal price in prices)

{

Console.WriteLine("{0, 22:F}", price);

subtotal += price;

}

Console.WriteLine(" -------");

Console.WriteLine("Sub-total {0, 7:F}", subtotal);

decimal tax = Math.Round(subtotal * .09m, 2);

Console.WriteLine("Tax @ 9% {0, 7:F}", tax);

Console.WriteLine(" -------");

Console.WriteLine("Grand total {0, 7:F}", subtotal + tax);

Console.WriteLine(" =======");

Console.WriteLine("\nThank you for your custom. Have a nice day!");

}
