我收到错误告诉我应该使用==来分配变量 [英] I am getting an error telling me I should use == for assigning a variable

问题描述

我已经编写了这段代码来测试我正在编写的一些代码，只有在我使用==而不是=：



#include< iostream>

使用命名空间std;

int main（）

{

int internal_organ_cream = 5;

int liquid_organs = 7;

& internal_organ_cream =& liquid_organs;

}



我尝试像这样运行它，但它没有工作，但当我改变= = = =它工作。我不明白为什么因为我认为==当你在分配时不检查因为在这里我试图让internal_organ_cream成为liquid_organs的参考。



< b>我尝试了什么：



没有...................... ..............................................

I have written this code to test something for some code I am writing and it only works if I use == rather than =:

#include <iostream>
using namespace std;
int main ()
{
int internal_organ_cream = 5;
int liquid_organs = 7;
&internal_organ_cream = &liquid_organs;
}

I tried running it like this but it didnt work but when I changed the = to a == it worked. I dont understand why because i thought == was for when you are checking not when you are assigning because here i am trying to make internal_organ_cream a reference of liquid_organs.

What I have tried:

nothing....................................................................

推荐答案

这是因为&在 internal_organ_cream 前面 - 删除它们并且它将起作用：

It's because of the "&" in front of internal_organ_cream - remove them both and it will work:

int internal_organ_cream = 5;
int liquid_organs = 7;
internal_organ_cream = liquid_organs;

当你输入&在变量名称前面，它返回变量的地址，而不是它的内容 - 但是当你到达指针时将会在后面解释。目前，根本就不要使用它们！

When you put "&" in front of a variable name, it returns the address of the variable, rather than it's content - but that will be explained later when you get to pointers. For the moment, just don't use them at all!
