从初始百分比中减去，但仅当用户输入时；否"/假C#

在我的代码中，接下来的问题是，我有几个if语句需要用户输入。我想设置一个数字（100），如果用户输入=no，那么x number从100中扣除，但是我需要它，比如说第一个用户说no，（100-y）=a，然后第二个用户说no，他的值将扣除a-y

这些计数器正在用于其他用途。我对C#有点陌生，希望它有意义，感谢所有的帮助

我也不明白你到底想要什么。如果你有更多的问题问。我对C也是新手，我可以告诉你，它不是Python语言：-）

我将以以下方式处理它。数一数你问这个问题的次数。计算每个问题的答案。显示结果

        double numberAsked = 0;
        double yesIcecream = 0, noIcecream = 0, maybeIcecream = 0;
        while (true) // have a nice way to exit in your app
        {
            Console.WriteLine("Do you like Ice cream? ");
            string answer = Console.ReadLine();
            numberAsked++;
            if (answer == "yes")
            {
                yesIcecream++;
            }
            else if (answer == "no")
            {
                noIcecream++;
            }
            else if (answer == "maybe")
            {
                maybeIcecream++;
            }

            Console.WriteLine($"yes: { yesIcecream / numberAsked * 100}%");
            Console.WriteLine($"no: { noIcecream / numberAsked * 100 }%");
            Console.Write($"maybe: { maybeIcecream / numberAsked * 100 }%\n\n");
        }

无法理解您的问题发布您的试用代码，您发布的代码似乎不是您的试用代码`然后x数字从100中扣除，但我需要它，所以请说出第一个说不的用户，（100-y）=a`哪里是

y

的来源？C#或者不是，您可以访问的只是循环和分支（如果，开关语句），乐高有更多的自由度。因此，当您调试此代码并逐步完成代码时，您是否知道哪些不适合您？这里的关键词是debug，真的不清楚。这段代码中有很多奇怪的东西。变量名。一些指定属性
