Hi,

I'm new in c# and i'm trying to print a receipt. but my codes are wrong, Here is my problem

> Compute the Price multiplied by the quantity given by the user
> Compute the said Amount - 12% tax
> Show the Vat Tax
> Accept money and compute the change
> they have to all appear once the unit price has been inputted

This are my codes at the moment for the computation part

bool test = false;
do
{
    try
    {
        Console.SetCursorPosition(2, 12);
        Console.Write("       ");

        Console.SetCursorPosition(2, 12);
        Num = Convert.ToInt32(Console.ReadLine());
        test = false;
    }
    catch
    {
        test = true;
    }
} while (test);

Console.SetCursorPosition(18, 12);
Console.ForegroundColor = ConsoleColor.Yellow;
telNumber = Console.ReadLine();

//Peso

bool Ptest = false;
do
{
    try
    {
        Console.SetCursorPosition(47, 12);
        Console.Write("       ");
        Console.SetCursorPosition(47, 12);
        Amount = Convert.ToInt32(Console.ReadLine());
        Console.SetCursorPosition(65, 12);
        Amount = Amount * 2 ;
       
        Console.WriteLine("P   " + Amount.ToString("0.00"));

        Console.SetCursorPosition(65, 15);
        Console.ForegroundColor = ConsoleColor.Green;
        Console.WriteLine("P   " + Amount.ToString("0.00"));

        Console.SetCursorPosition(65, 17);
        Console.ForegroundColor = ConsoleColor.Green;
        Console.WriteLine("P   " + Amount.ToString("0.00"));
          
        Ptest = false;
    }
    catch
    {
        Ptest = true;
    }
} while (Ptest);

//Amount

Console.ReadLine();

它必须看起来像这样，我已完成格式但我遇到上述问题的麻烦，请帮助

推荐答案

我们不做你的作业：它是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，你可能会发现它不是和你想的一样困难！



如果遇到具体问题，请询问相关问题，我们会尽力提供帮助。但是我们不会为你做这一切！



到目前为止，你已经完成了外部结构，但没有尝试进行任何实际的计算。

你知道如何繁殖，你知道百分比是多少：所以（正如比尔所说）将整数转换为双精度，并尝试添加代码来进行计算：这不是一项复杂的任务如果你自己无法解决这个问题，那么下一个作业任务将会遇到麻烦！

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

And so far, you have done the outside structure, but not tried to do any of the actual computations.
You know how to multiply, you know what a percentage is: so (as Bill says) convert your integers to doubles, and try adding the code to do the computations: this is not a complex task, and if you can't work out how to do this yourself, you are going to have real trouble with your next homework task!
