将数组传递给函数 [英] Passing an array to a function

问题描述

您好，



我正在尝试编写此程序的问题。我首先在主要内部编写了程序。然后我试图将程序划分为单独的函数。我遇到的更具体的问题发生在第一个函数的开头。第一个大括号提示我这个错误：类，结构或接口成员减速中的无效标记'{'。任何有关这方面的帮助将不胜感激。

Hello,

I am having a problem with this program that I am trying to write. I first wrote the program within the main. Then I attempted to divide the program into separate functions. The more specific problem that I am having occurs right at the beginning of the first function. The first curly brace prompts me with this Error: Invalid Token '{' in class, struct, or interface member deceleration. Any help with this would be greatly appreciated.

        static void Main(string[] args)
        {

            int totalScore = 0, avgScore = 0, i = 0, count = 0;
            string[] names = new string[100];
            int[] scores = new int[100];

            //Jumpt to module 1
            InPutData(names, scores, ref count);

          for (i = 0; i < count; i++)
              if (scores[i] < avgScore)
              {

推荐答案

引用：

public static void InPutData（string [] names，int []得分，ref int count） ;

public static void InPutData(string[] names, int[] scores, ref int count);

删除行尾的分号。

Remove the semicolon at the end of the line.

那是因为你正在使用行终止符（有人告诉我这个字符的真实姓名）你的代码中有; ，这就是为什么编译器不期望 {代码中的令牌并给出了此错误。



请参阅您的代码，

That is because you're using a line terminator (someone tell me the real name of this character) there ; in your code, that is why the compiler was not expecting the { token in the code and gave this error.

See in your code,

public static void InPutData(string[] names, int[] scores, ref int count); // <--
{

删除它，现在就会这样，

Remove it, and it will be like this now,

public static void InPutData(string[] names, int[] scores, ref int count)
{

..现在它不会抱怨。 :-)



此外，毕竟没有错误传递数组，也没有错误。

.. now it won't complain. :-)

Also, there was no error passing array after all and there won't be an error.
