无法在我的代码中找到错误 [英] Unable to find the error in my code

问题描述

有人可以查看下面的代码并提出问题区域。

Can someone please check the code below and mention the problem area.

<pre>static void Main(string[] args)
        {
            Console.Write("How many nums to be compared: ");
            int n = int.Parse(Console.ReadLine()); //Parse int n for arr.Length
            int[] arr = new int[n]; //Creates array with name arr and length n
            Console.WriteLine("Enter the nums: "); //To be used while entering elements

            //Registers array elements
            for (int arrIndex = 0; arrIndex < arr.Length; arrIndex++)
            {
                arr[arrIndex] = int.Parse(Console.ReadLine()); //Parse array elements
            }

            //Prints array
            for (int arrIndex = 0; arrIndex < arr.Length; arrIndex++)
            {
                Console.Write(arr[arrIndex] + " ");
            }
            Console.WriteLine();

            GetMax(arr);
        }

        static void GetMax(int[] array)
        {
            if ((array[0]) > (array[1]))
            {
                Console.Write("Number {} is > than {}", array[0], array[1]);
            }
            else if ((array[0]) < (array[1]))
            {
                Console.Write("Number {} is < than {}", array[0], array[1]);
            }
            else
            {
                Console.Write("Number {} and {} are equal", array[0], array[1]);
            }
        }}

我尝试了什么：



我试着从我正在学习C＃的书中重新阅读有关方法的完整章节，但找不到任何理由。



我是一个绝对的初学者，所以我请求保持解释非常简单。



当我运行代码时，它给我以下错误< br $>

What I have tried:

I tried re-reading the complete chapter on methods from the book I'm learning C# but couldn't find any reason.

I'm an absolute beginner so I request to please keep the explanation very very simple.

It gives me the following error when I run the code

How many nums to be compared: 2
Enter the nums:
1
5
1 5

推荐答案

您的问题出在 Console.Write 函数中 - 您忘记了将变量的索引放在输出中。你还应该在 Main 方法的末尾添加一个 Console.ReadKey（）; ，因为你会这样，否则，从Visual Studio启动程序时看不到输出...

Your problem is in the Console.Write function - you forgot to put the index for the variable to be shown in the output. You should also add a Console.ReadKey(); call at the end of the Main method because you will, otherwise, not see the output when you start the program from Visual Studio...

static void GetMax(int[] array)
        {
            if ((array[0]) > (array[1]))
            {
                Console.Write("Number {0} is > than {1}", array[0], array[1]);
            }
            else if ((array[0]) < (array[1]))
            {
                Console.Write("Number {0} is < than {1}", array[0], array[1]);
            }
            else
            {
                Console.Write("Number {0} and {1} are equal", array[0], array[1]);
            }
        }

感谢你指出这一点。



下次我将在重新检查我的代码时更加专注。



再次感谢。是的，该计划现在正在运作。

Thanks for pointing that out.

Next time i will be more attentive while rechecking my codes.

Thanks again. Yes the program is working now.
