如果有人指导我，我所做的一切都是正确的，或者帮助我理解上述问题的要求？ [英] If someone direct me whatever I have done is correct or help me understand what above question is asking for?

问题描述

我被要求编写一个名为Magic的类。包括私有int成员字段spiders和toads及其属性，包括get和set函数。还包括一个名为do_Magic（）的公共void成员函数，它打印出Poooofff。最后包括2个构造函数，一个不带参数的构造函数，并设置toads和spider都等于0;一个接受两个int参数，并设置等于第一个参数的toads和等于第二个参数的spiders。在Main（）中，我试图创建一个实例myMagic，并将值3,5分别分配给toads和spiders。

我已经编写了输出Poooofff的代码，但我不知道它是写还是错。我很困惑这个程序的输出是什么？如果有人指导我，我所做的一切都是正确的，或者帮助我理解上述问题的要求？

 {
  class  Magic 
 {
  private   int 蜘蛛; 
  public   int 蜘蛛
 {
  set  
 {
 spiders =  value ; 
} 
 获取 
 {
 返回蜘蛛; 
} 
} 
 
 私人  int  toads; 
  public   int  Toads 
 {
  set  
 {
 toads =  value ; 
} 
  get  
 {
  return  toads; 
 
} 
} 
  public   void  do_myMagic（ ）
 {
 spiders =  0 ; 
 toads =  0 ; 
 Console.WriteLine（  Pooofff）; 
 
} 
  public   void  do_myMagic（ int  arg1， int  arg2）
 {
 toads = arg1; 
 spiders = arg2; 
} 
  class 计划
 {
 静态 < span class =code-keyword> void  Main（）
 {
 Magic myMagic =  new  Magic（）; 
 myMagic.spiders =  5 ; 
 myMagic.toads =  3 ; 
 myMagic.do_myMagic（）; 
} 
} 
} 

解决方案

你越来越近但你对构造函数的理解不足。



开始阅读构造函数：

C＃中的构造函数介绍 [ ^ ]



do_MyMagic（）只需要这样：

  public   void  do_myMagic（）
 {
 Console.WriteLine（  Pooofff）; 
 
} 

你现在需要2个施工人员：

  class  Magic {
  public  Magic（ ）
 {
  //   code  
} 
 
  public  Magic（ int  iToads， int  iSpiders）
 {
  //   code  
} 
} 

我不会做其余的事 - 你似乎很有能力。



然后你就可以写：

 Magic myMagic =  new  Magic（ 3 ， 5 ）; 
 

现在加在顶部

 使用系统; 
 
 命名空间家庭作业

及以下< pre lang =cs> myMagic.do_myMagic（）;

添加行

 Console.ReadKey （）;  //  点击键 - 停止立即退出。 
 

这应该编译并运行打印出pooff。然后你可以玩set get例如：

 Console.WriteLine（myMagic.Spiders）; 
 myMagic.Spiders =  9 ; 
 Console.WriteLine（myMagic.Spiders）; 

我同意Bill的评论。

构造函数名称应与Class的名称相同：因此，使用

 public Magic（）
 public Magic（int arg1，int arg2）

do_myMagic应该是返回Type为void的方法/函数的名称，它只是将字符串值写入您希望输出的任何内容：

 public void do_myMagic（）
 {
 / /你的代码要做什么
} 

在我的拙见中，无论谁给你这个任务都没有资格教授编程：这是一项愚蠢而无用的任务。



我建议您获得一本关于C＃编程的好书，并开始编写能够真正教给你的代码示例。

I am asked to write a class called "Magic." Include private int member fields spiders and toads and their properties, which include get and set functions. Also include a public void member function called do_Magic(), that print out "Poooofff". And finally include 2 Constructors, one that takes no arguments, and sets toads and spider both equal 0; one that takes two int arguments, and sets toads equal to the first argument and spiders equal to the second argument. In Main(), I am trying to create an instance myMagic and assign the values 3,5 to toads and spiders, respectively.
I have wrote the codes that output Poooofff, but I don’t know it that is write or wrong. I am confused what this program’s output would be? If someone direct me whatever I have done is correct or help me understand what above question is asking for?

{
    class Magic
    {
        private int spiders;
        public int Spiders
        {
            set
            {
                spiders = value;
            }
            get
            {
                return spiders;
            }
        }

        private int toads;
        public int Toads
        {
            set
            {
                toads = value;
            }
            get
            {
                return toads;

            }
        }
        public void do_myMagic()
        {
             spiders= 0;
             toads = 0;
            Console.WriteLine("Pooofff");

        }
        public void do_myMagic(int arg1, int arg2)
        {
             toads = arg1;
            spiders = arg2;
        }
        class Program
        {
            static void Main()
            {
                Magic myMagic = new Magic();
                myMagic.spiders = 5;
                myMagic.toads = 3;
                myMagic.do_myMagic();
            }
        }
    }

解决方案

You are getting close but your understanding of constructors is deficient.

To begin read up on constructors:
An Intro to Constructors in C#[^]

do_MyMagic() only needs this:

public void do_myMagic()
{
     Console.WriteLine("Pooofff");

}

You now need 2 constructors:

class Magic {
public Magic()
{
// code
}

public Magic(int iToads, int iSpiders)
{
// code
}
}

I won't do the rest - you seem quite capable of that.

Then you will be able to write:

Magic myMagic = new Magic(3, 5);

[EDIT] Now add at the top

using System;

namespace Homework

And below

myMagic.do_myMagic();

add the line

Console.ReadKey(); // Hit key - Stops from exiting immediately.

This should compile and run printing out "pooff". Then you can play around with set get eg:

Console.WriteLine(myMagic.Spiders);
myMagic.Spiders = 9;
Console.WriteLine(myMagic.Spiders);

I agree with Bill's comments.

Constructor names should be the same name as the Class: so, use

public Magic()
public Magic(int arg1, int arg2)

do_myMagic should be the name of a method/function with return Type 'void that simply writes the string value to whatever you wish to output it to:

public void do_myMagic()
{
    // your code to do whatever
}

In my humble opinion, whoever gave you this "task" is unqualified to teach programming: it is a silly, and useless, assignment.

I recommend you get a good book on C# programming, and start working on code examples that will really teach you something.
