问题描述
我的编译器（m68k-gcc）不允许这样（简化示例;不是我的
真实代码），我不明白为什么不：
{
char * arrayCharPtr1 [] = {" a"，" ab"，NULL};
char * arrayCharPtr2 [] = {" A"，" AB"，NULL};
char * arrayCharPtrVar [] =
（（someBoolean）？arrayCharPtr1：arrayCharPtr2）; //< -error here！
StrCopy（someString，arrayCharPtr [0]）;
}
我也有尝试过=& arrayCharPtr1 [0]我认为应该工作，
;它没有。
我缺少什么？如何做到这一点？
My compiler (m68k-gcc) does not allow this (simplified example; not my
real code) and I don''t see why not:
{
char *arrayCharPtr1[] = {"a", "ab", NULL};
char *arrayCharPtr2[] = {"A", "AB", NULL};
char *arrayCharPtrVar[] =
((someBoolean) ? arrayCharPtr1 : arrayCharPtr2); // <-error here!
StrCopy(someString, arrayCharPtr[0]);
}
I have also tried "= &arrayCharPtr1[0]" which I assumed should work,
too; it doesn''t.
What am I missing? How can this be done?

你究竟想做什么？

就像我说的那样。

PS：你的命名约定也是幼稚的。 CharPtr没用，Var是变量名无意义的。
使用像lower_strings []和upper_strings []这样的名字......
Like I say.

PS: also your naming conventions are childish. CharPtr is useless, Var is
meaningless in variable names.
Use names like lower_strings[] and upper_strings[]...
声明一个未知大小的数组只接受一个聚合的初始化器（即''{}'' - 封闭的初始化器）。你提供的那个不是。
Declaration of an array of unknown size will only accept an aggregate
initializer (i.e. ''{}''-enclosed initializer). The one you provided is not.

你做了一个相当不错的编译器模仿：非常准确，而且
完全没用。
我*知道*我不能做我想做的事情我想做的事
（编译器非常清楚）;这就是为什么我给出了
完整的上下文，显示了我想做的事情。我几乎不能更多
清楚。
我必须使用字符串数组。
我想分配一个或另一个数组到一个变量，这样我就可以用数组var [index]来索引数组中的任何字符串。
这很简单，我肯定不是不可能的。 ..
You do a pretty good compiler immitation: perfectly accurate and
totally worthless.
I *KNOW* I cannot do what I want to do the way I am trying to do it
(the compiler is quite clear about that); That''s why I gave the
complete context showing WHAT I want to do. I can hardly be more
clear.
I have to arrays of strings.
I want to assign one or the other array to a variable such that I can
index any string in the array with something like var[index].
It is very simple and I am quite sure not impossible...
