输入铸造和铸造操作员 [英] Type casting and cast operators

问题描述

查看以下程序

在可编辑部分的适当类中编写适当的构造函数/转换运算符，以使函数convert（）可行，将非展开式转换为unrelat_1类类型。

 
  #include   <   iostream  >  
  
 使用 命名空间标准; 
 
  class  unrelat {}; 
  class  unrelat_1 {}; 
 
 
 
 
 
  int 转换（ class  unrelat_1& c， class  unlat& d）{
  int  i =  5 ; 
 cin>>一世 ; 
 c = d; 
 c = static_cast< unrelat_1>（d）; 
 c =（unrelat_1）d; 
  return （i * 10 + 35）; 
} 
  int  main（）{
  int  out; 
 unrelat_1 a; 
 unlat b; 
 out =转换（a，b）; 
 cout<<出去
  return   0 ; 
} 

我的尝试：

 
使用命名空间std; 
 
 class unrelat {}; 
 class unrelat_1： public unrelat {}; 
 
 unrelat_ * d = new unrelat（）; 
 unrelat_1 * c = static_cast< unrelat *>（d）; 
 
 
 
 int转换（class unrelat_1& c，class unrelat& d）{
 int i = 5; 
 cin>> i; 
c = d; 
c = static_cast< unrelat_1>（d）; 
c =（unrelat_1）d; 
 return（i * 10 + 35）; 
} 
 int main（）{
 int out; 
 unrelat_1 a; 
 unrelat b; 
 out =转换（a，b）; 
 cout<< out; 
返回0 ; 
} +> 
 

解决方案

我们不做你的作业：它是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，你可能会发现它不是和你想的一样困难！



如果遇到具体问题，请询问相关问题，我们会尽力提供帮助。但是我们不打算为你做这一切！

'文档' [ ^ ] ？

你没有说出任何问题，你没有问任何问题，你没有尝试任何事情。



不，我们不做你的HomeWork。

HomeWork不会测试你乞求别人做你的工作的技巧，它会让你思考并帮助老师检查您对所学课程的理解以及您应用这些课程时遇到的问题。

你的任何失败都会帮助你的老师发现你的弱点并设定补救措施。

你的任何失败都会帮助你了解什么有效，什么无效，被称为'试错'学习。

所以，试一试，重读课程并开始工作。如果您遇到特定问题，请展示您的代码并解释这个问题，我们可能会提供帮助。

Look at the Following program
Write proper constructor/conversion operator in appropriate class in editable section to make function convert( ) workable, which cast/convert unrelat to unrelat_1 class type.

​
#include <iostream>

 using namespace std;

class unrelat{ };
class unrelat_1 { };





int Convert( class unrelat_1 &c, class unrelat &d){
         int i = 5;
         cin >> i ;
         c = d;
         c = static_cast<unrelat_1>(d);
         c = (unrelat_1)d;
         return (i*10+35) ;
}
     int main() {
         int out;
         unrelat_1 a;
         unrelat b;
         out = Convert(a, b);
         cout << out ;
         return 0;
     }

What I have tried:

解决方案

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

What about 'the documentation'[^]?

You didn't stated any problem, you didn't asked any question, you didn't tried any thing.

No, we do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.
