按字符串名称访问 [英] Access by string name

问题描述

我想知道是否可以访问变量

，其名称存储在另一个字符串变量。

例如：


int myInt = 10;

char * myName =" myInt";


是否可以通过myName访问myInt？


谢谢。

不确定，但我认为不是。据我所知，在编译（链接）之后，

名称消失了。但是我认为你可以实现类似

这样的东西，不应该那么难......

可能我需要更好地理解你的问题。 ？

您是否询问编译器（内部）如何跟踪每个

变量或类似的事件？

我认为Java通过反射完成了这项工作，所以选择那种语言

将节省很多时间。

Hi,

I''d like to know whether it''s possible to access a variable
by its name of which is stored in another string variable.
For example:

int myInt=10;
char *myName="myInt";

Is it possible to access myInt only through myName?

Thanks.

Not sure, but I think no. As far as I know, after compiling (linking),
the names are gone. But I think you could implement something like
that by yourself, should not be that hard..

May be I need to better understand your question. ?
Are you asking how compiler (internally) tracking occurence of each
Variable or something like that ?

I think Java have done the job by reflection, so choose that language
will save a lot time.
