显示数字1到100的和和平均值

本文关键字：平均值 数字 显示 | 更新日期: 2023-09-27 18:06:01

我正试图用c#写一个简单的程序来显示数字1到100的总和和平均值。输出应该看起来像…

the sum is 5050
the average is 50.5

我似乎不能让它正常工作，虽然，返回值只返回总和不是它之前的措辞，我已经尝试了其他的方式来显示消息和总和，但他们不工作。我试图使用模型视图视图控制器方法做到这一点，但无法理解我在哪里出错以及如何让它显示上述结果。我的代码如下:

class SumAndAverage
{
    public float sum = 0;
    public float ave = 0;

    public float SumAndAve()
    {
        for (int i = 1; i <= 100; i++)
        {
            sum = sum + i;
            ave = sum / i;
        }
        return sum + ave;
    }
}

} 

class SumAndAverageController
{
    IView view;
    SumAndAverage sumAndAverage;
    public SumAndAverageController(IView theView, SumAndAverage theSumAndAverage){
    view = theView;
    sumAndAverage = theSumAndAverage;
}
    public void Go()
    {
        view.Start();
        //mAndAverage.SetNumber(view.GetString("Please enter a number"));
        view.Show(sumAndAverage.SumAndAve());
        //view.Show(sumAndAverage.Result());
        view.Stop();
    }
}

class ConsoleView : IView
{
    public void Start()
    {
        Console.Clear();
    }
    public void Stop()
    {
        Console.WriteLine("Press any key to continue");
        Console.ReadKey();
    }

    public void Show<T>(T message)
    {
        Console.WriteLine(message);
    }
}

interface IView
{
    void Start();
    void Stop();
    void Show<T>(T message);
}

class Program
{
    static void Main(string[] args)
    {
        new SumAndAverageController(new ConsoleView(), new SumAndAverage()).Go();
    }
}

显示数字1到100的和和平均值

using System;
using System.Linq;
namespace SumAndAverage
{
    class Program
    {
        static void Main(string[] args)
        {
            var data = Enumerable.Range(1, 100);
            Console.WriteLine("the sum is " + data.Sum());
            Console.WriteLine("the average is " + data.Average());
        }
    }
}
