三维数组初始化
在我正在查看的一些代码中，一个 3D 数组已像这样初始化：（
static const char codeset[6][256][10] = {
[0] = { [0x20] = " ",
[0x21] = "!",
[0x22] = """,
[0x23] = "#",
}};
它确实继续初始化其余单元格，我已将其剪短以显示可读的内容。）
这不会编译。是应该的吗？这是怎么回事？
In a bit of code I'm looking at, a 3D array has been initialized like so:
static const char codeset[6][256][10] = {
[0] = { [0x20] = " ",
[0x21] = "!",
[0x22] = """,
[0x23] = "#",
}};
(It does go on to initialize the rest of the cells, I've cut it short to show something readable.)
This does not compile. Is it supposed to? What's going on here?

作为猜测，它试图为 xml 字符串 ASCII 数据创建“字母表”。 xml 中的 "（双引号）字符表示为 "。因此 [0][0 - 255] 组是 xml。
它看起来像一个等价表。它从 xml 转换为 ASCII 或其他形式。
As a guess, it trying to create the "alphabet" for xml string ASCII data. The " (double quote) character in xml is represented as ". So the [0][0 - 255] group is xml.
It looks like an equivalence table. It translates from xml to ASCII or whatever.
您正在使用 C99 初始值设定项，但您的编译器不支持 C99 或未启用 C99。
You are using C99 initializers, but your compiler does not support C99 or C99 is not enabled.
您正在尝试使用 C99 初始化程序，但很可能您的编译器不是' t C99 兼容，否则它可以工作。
You are trying to use C99 initializers, but most likely your compiler isn't C99-compliant, otherwise it would work.
