如此數(shù)組定義...

小丌

各位有看到過這種定義數(shù)組的方式么？這種定義是什么意思？我是在一個(gè)拼音函數(shù)中看到的，我省了一些，在直接在VC下編譯不過去？大俠指教...
static unsigned short pinyinsort[] =
{
        [1] = 0x01,
        [5] = 0x02,
        [2] = 0x02,
        [4] = 0x04,
        [0] = 0x05,
        [3] = 0x06,
};

LF_532

個(gè)人感覺，還是給數(shù)組賦值。 只不過是在大括號內(nèi)進(jìn)行了顯示地賦值。
主要作用應(yīng)該是用來實(shí)現(xiàn)各個(gè)拼音的組合。

vc 6.0只支持c95以前的,所以不編譯通不過,gcc兼容絕大多數(shù)c99語法

Designated Initializers (C99)
C99 has added a new capability?designated initializers. This feature allows you to pick and choose which elements are initialized. Suppose, for example, that you just want to initialize the last element in an array. With traditional C initialization syntax, you also have to initialize every element preceding the last one:

int arr[6] = {0,0,0,0,0,212};  // traditional syntax

With C99, you can use an index in brackets in the initialization list to specify a particular element:

int arr[6] = {[5] = 212}; // initialize arr[5] to 212

As with regular initialization, after you initialize at least one element, the uninitialized elements are set to 0.

以上摘自 C Primer Plus 5e
