Problem white foodVATRate

johan s

Hi.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Uppgift_1
{
    class Product
    {
        private string Produuct;
        private decimal Price;
        private decimal Vat;
        private bool Food;
        private int Count;

        private const decimal foodVATRate = 0.12m, otherVATRate = 0.25m;
        private decimal Finalprice;
        private decimal Rate;

        public void Readinput()
        {
            Console.Write("\n\nWhat is the product you want: ");
            Produuct = Console.ReadLine();

            Console.Write("Unit price: ");
            decimal.TryParse(Console.ReadLine(), out Price);

            Console.Write("Food item y/n: ");
            char answer = char.Parse(Console.ReadLine());
            if ((answer == 'y') || (answer == 'Y'))
                Food = true;
            else
                Food = false;

            Console.Write("Count: ");
            int.TryParse(Console.ReadLine(), out Count);

            Finalprice = (decimal)(Price * Count);

        }

        private void cal()
        {
            char answer = char.Parse(Console.ReadLine());
            if ((answer == 'y') || (answer == 'Y'))
                Vat = foodVATRate;
            else
                Vat = otherVATRate;

            Rate = Finalprice * Vat;
        }

        public void PrintRecept()
        {
            Console.Write("\n++++++++++++++++++++++++++++++++++++++++++++++++++++++");
            Console.Write("\n\nThe product you want is: " + Produuct);
            Console.Write("\nThe price: "+ Price);
            Console.Write("\nFood item: "+Food);
            Console.Write("\nCount: "+Count);
            Console.Write("\n\nTotal price: "+Finalprice);
            Console.Write("\nVAT at: " +Rate);
            Console.Write("\n\n++++++++++++++++++++++++++++++++++++++++++++++++++++++");
        }
    }

    }

Can any way tell my way i don't get any thing in Console.Write("\nVAT at: " +Rate);?

OK, in that case you can get rid of the cal() method as you can do all the calculations in the Readinput() method:

public void Readinput()
{
Console.Write("Food item y/n: ");
char answer = char.Parse(Console.ReadLine());

if ((answer == 'y') || (answer == 'Y'))
{
Food = true;
Vat = foodVATRate;
}
else
{
Food = false;
Vat = otherVATRate;
}

Finalprice = Price * Count;
Rate = Finalprice * Vat;
Finalprice += Rate;
}

thx but i probably don't tell that good what i whant.
I mean when i come to the line to show if it is a food or noot. When i press Y it will show the foodVATRate. so when i come to the final price it will take the
finalprice and * it white the food question like if i press y is going to be finalprice*foodVATRate and it will be the VAT

These points can be deal with by making the highlighted changes:

public void cal()
{
Console.Write("Food VAT Rate y/n: ");
char answer = char.Parse(Console.ReadLine());
if ((answer == 'y') || (answer == 'Y'))
Vat = foodVATRate;
else
Vat = otherVATRate;
Rate = Finalprice * Vat;
Finalprice += Rate;
}

public void PrintRecept()
{
Console.Write("\nFood item: "+Food);
Console.Write("\n\nTotal price: "+Finalprice);
Console.Write("\nincluding VAT at " + (Vat * 100m) + "% : " + Rate);
}

thx for the help white that but i wanted same thing diffrent. When i press y in the food question the foodVATRate and when i press n the otherVATRate.

and the Console.Write("\nVAT at " + (Vat * 100m) + "% : " + Rate); dident help me in my.

and i can get the cal(); in to my.

    static void Main(string[] args)
        {
            Console.Title = "Tax Calculator";
            Product obj = new Product();
            obj.Readinput();
            obj.PrintRecept();
            Console.WriteLine("\n\n\nPress enter to exit");
            Console.ReadLine();

for i get a Error Product.cal()' is inaccessible due to its protection level

That was the problem you haven't added the functions calls, hence you are not getting the result. Apart from that everything else is fine.

There should be someone who should call Readinput(), cal() and PrintRecept() functions right. That is what you missed. Add those then your code should work fine i hope

I've just created a 'rough and ready' console version of this program:

using System;

class Program
{
static void Main()
{
Program p = new Program();
Console.Write("Price : ");
p.Price = Decimal.Parse(Console.ReadLine());
Console.Write("Count : ");
p.Count = Int32.Parse(Console.ReadLine());

p.Readinput();
p.cal();
p.PrintRecept();
}

private int Count;
private decimal Price;
private decimal Vat;
private bool Food;

private const decimal foodVATRate = 0.12m, otherVATRate = 0.25m;
private decimal Finalprice;
private decimal Rate;

public void Readinput()
{
Console.Write("Food item y/n: ");
char answer = char.Parse(Console.ReadLine());
if ((answer == 'y') || (answer == 'Y'))
Food = true;
else
Food = false;

Finalprice = (decimal)(Price * Count);

}

private void cal()
{
Console.Write("Food VAT Rate y/n: ");
char answer = char.Parse(Console.ReadLine());
if ((answer == 'y') || (answer == 'Y'))
Vat = foodVATRate;
else
Vat = otherVATRate;
Rate = Finalprice * Vat;
}

public void PrintRecept()
{
Console.Write("\nFood item: "+Food);
Console.Write("\n\nTotal price: "+Finalprice);
Console.Write("\nVAT at: " +Rate);
}
}

The line which you say doesn't show anything does in fact show the VAT on the transaction.

If you want to show the VAT rate as well, then change that line to:

Console.Write("\nVAT at " + (Vat * 100m) + "% : " + Rate);

You aren't showing the whole code, check the function calls properly or else show the code completely. There are no function calls as far as the above code is concerned.
