变量的别名 [英] alias for a variable

问题描述

嗨朋友们，


我们可以在C中使用变量的别名。


就像我定义一个int ---

int示例;


现在我想要另一个变量，即示例的别名。我

意味着示例和另一个变量让我们说example2拥有相同内存的

，但我们正在用两个变量进行渲染。

我需要两者都是全局变量。


我不是在谈论通过引用进行调用，而是可以使用#define。我是吗？


问候，

Paresh

Hi Friends,

Can we have a alias of a variable in C.

Like I define an int---
int example;

Now I want another variable that is the alias for the "example". I
meant both example and another variable let say "example2" have the
same memory but we are refrencing with it by two variables.
I need both to be global variables.

I am not talking about call by reference and I can use #define. Am I?

Regards,
Paresh

是的，您可以使用#define，或者您只需将两个指针指向

同一个对象。

Yes, you could use #define, or you could simply point two pointers at
the same object.

我需要两者都是全局变量。

I need both to be global variables.

为什么你需要这样做？

Why on earth would you need to do that?

我不是在谈论参考电话

I am not talking about call by reference

C中没有这样的东西。

No such thing in C.

我可以使用#define。

and I can use #define.

是的，你可以。

Yes, you can.

我？

Am I?

你是什么？

Are you perhaps looking for a union?

不，我不是在寻找工会。是的，最简单的方法是

#define。

还有其他办法吗？

No I am not looking for union. Yes the easiast way to do this is
#define.
Is there any other way?
