Question

我刚开始学习循环，我不明白如何使用for或while语句在输出中累积多个总数。

我的代码是代表三个家庭（A，B和C）有车库出售。当他们输入姓名缩写时，他们可以输入一笔销售金额。他们可以根据需要添加任意数量的金额，当他们想看到他们的总数时，他们按 Z 它将显示每个家庭的总数，以及在车库出售时的总额。 / p>

我无法弄清楚如何显示所有总数。我应该怎么做呢？

这是我到目前为止所做的：

static void Main(string[] args)
{
    double totalFamilyA;
    double totalFamilyB;
    double totalFamilyC;
    double grandTotal = 0;
    double saleAmount;
    string familyInitial;
    string inputSale;
    Console.Write("Enter your family initial A, B, or C (uppercase/lowercase accepted) ");
    familyInitial = Console.ReadLine();
    Console.Write("Enter sale amount $");
    inputSale = Console.ReadLine();
    saleAmount = Convert.ToDouble(inputSale);

    while (familyInitial != "Z" && familyInitial != "z")
    {
        totalFamilyA = Convert.ToDouble(inputSale);
        totalFamilyB = Convert.ToDouble(inputSale);
        totalFamilyC = Convert.ToDouble(inputSale);
        if (familyInitial == "A" || familyInitial == "a")
        {
            totalFamilyA += saleAmount;
            Console.Write("Enter next sale amount or press 'Z' or 'z' to see the grand total $");
            inputSale = Console.ReadLine();
            saleAmount = Convert.ToDouble(inputSale);
            totalFamilyA = Convert.ToDouble(saleAmount);
        }
        else if (familyInitial == "B" || familyInitial == "b")
        {
            totalFamilyB += saleAmount;
            Console.Write("Enter next sale amount or press 'Z' or 'z' to see the grand total $");
            inputSale = Console.ReadLine();
            saleAmount = Convert.ToDouble(inputSale);
            totalFamilyB = Convert.ToDouble(saleAmount);
        }
        else if (familyInitial == "C" || familyInitial == "c")
        {
            totalFamilyC += saleAmount;
            Console.Write("Enter next sale amount or press 'Z' or 'z' to see the grand total $");
            inputSale = Console.ReadLine();
            saleAmount = Convert.ToDouble(inputSale);
            totalFamilyC = Convert.ToDouble(saleAmount);
        }
    }
    Console.WriteLine("Your total is {0}", grandTotal.ToString("C"));
}

Answer 1

听起来你想要这样的东西：

int familyACount = 0;
int familBCount = 0;
int familyCCount = 0;

while(_inputString.toLower()!="z")
{
    //Parse input text here to work out the initials and amount entered
    string initials = //Something
    int amount = //Something

    if(initials == familyAInitials) familyACount += amount;
    //Repeat for other two families
}

//Z has been entered, so output the totals

Debug.Print("Family A:"+familyACount);
//Repeat for other families

Debug.Print("Total:" + (familyACount + familyBCount + familyCCount));

你会想要找出在输入结束时获取值的最佳方法（我假设首字母和总数输入为一个字符串）并且你可能想要在整数中加倍，因为你正在处理有钱。

如果您也想要添加金额，也可以输出运行总计，如果输入文本不是一组首字母等，也可以输出提示“Z退出”。

祝你好运！

你不需要循环语句你可以简单地写下以下几行来实现你的目标

 public enum PersonIntial
    {
        Person1,
        Person2,
        Person3,
        All
    }
    public int Person1Acnt { get; set; }
    public int Person2Acnt { get; set; }
    public int Person3Acnt { get; set; }
    public int TotalSales { get; set; }

    private void ProcessInput(PersonIntial pInitail, int amount)
    {
        switch (pInitail)
        {
            case PersonIntial.Person1:
                {
                    Person1Acnt += amount;
                }
                break;

            case PersonIntial.All:
                {
                    TotalSales = Person1Acnt + Person2Acnt + Person3Acnt;
                }
                break;
        }
    }

将您的输入转换为枚举....... 并调用ProcessInput（）

由于

累计多个总数
