寻找一种方法来缩短我的代码

Question

这是我的代码：    static void Main(string[] args)    {        Console.Write("How many tests would you like to do? 1 to 10: ");        int tests = Convert.ToInt32(Console.ReadLine());        Console.WriteLine();    }有人可以帮我解决我的代码吗？我不知道我在做什么

制作一个数组int[] counts = new int[13]并使用counts[total]++;; 最后，循环它：

for(int i = 2 ; i <= 12 ; i++)

    // etc

（注意：您可以使用 11 个项目的数组并不断处理两个，但是......这可能不值得）

就像是：

static void Main()

{

    Console.WriteLine("Investigation 1");

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

    Console.WriteLine();

    Console.Write("How many sets of tests? 1 to 10: ");

    int sets = Convert.ToInt32(Console.ReadLine());

    Console.WriteLine();

    Random r = new Random();

    int[] counts = new int[13];

    for (int ctr = 0; ctr < 36 * sets; ctr++)

    {

        int a = r.Next(1, 7), b = r.Next(1, 7), total = a + b;

        Console.WriteLine($"Roll {(ctr + 1)}: {a} + {b} = {total}");

        counts[total]++;

    }

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

    Console.WriteLine();

    Console.WriteLine("Total  Expected  Actual");

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

    for(int i = 2; i <= 12; i++)

    {

        var expected = sets * (6 - Math.Abs(7 - i));

        Console.WriteLine($"  {i}        {expected}        {counts[i]}");

    }

}

对于直方图：

var maxCount = counts.Max(); // needs "using System.Linq;" at the top

for (int i = 2; i <= 12; i++)

{

    var width = ((Console.WindowWidth - 10) * counts[i]) / maxCount; // make it proportional

    Console.WriteLine($"{i}\t{new string('*', width)}");

}
