结构体变量定义，初始化问题

abnerle 2010-11-10 11:00:49

结构体定义如下：
struct key_pad_vaule
{
UTF16_T key_pad_MENU[32];
UTF16_T key_pad_VOL_UP[32];
UTF16_T key_pad_VOL_DOWN[32];
UTF16_T key_pad_PRO_UP[32];
UTF16_T key_pad_PRO_DOWN[32];
UTF16_T key_pad_INPUT[32];
};
初始化如下
static struct key_pad_vaule key_pad_button_vaule={
.key_pad_MENU[32] = {0x004D, 0x0045, 0x004E, 0x0055, 0};
.key_pad_VOL_UP[32] = {0x0056, 0x004F, 0x004C, 0x0020, 0x0055, 0x0050, 0};
.key_pad_VOL_DOWN[32] = {0x0056, 0x004F, 0x004C, 0x0020, 0x0044, 0x004F, 0x0057, 0x004E,0};
.key_pad_PRO_UP[32] = {0x0043, 0x0048, 0x0020, 0x0020, 0x0055, 0x0050, 0};
.key_pad_PRO_DOWN[32] = {0x0043, 0x0048, 0x0020, 0x0020, 0x0044, 0x004F, 0x0057, 0x004E,0};
.key_pad_INPUT[32] = {0x0049, 0x004E, 0x0050, 0x0055, 0x0054, 0};
};
GUN C编译器提示，.key_pad_MENU[32]，下标超出范围，但是我下标是32，只有5个元素啊，怎么会超出呢？？？

扫盲吧，什么是C99?

刚刚试了一下，这样是对的
{
.key_pad_MENU = {0x004D, 0x0045, 0x004E, 0x0055, 0}，
.key_pad_VOL_UP = {0x0056, 0x004F, 0x004C, 0x0020, 0x0055, 0x0050, 0}，
.key_pad_VOL_DOWN = {0x0056, 0x004F, 0x004C, 0x0020, 0x0044, 0x004F, 0x0057, 0x004E,0}，
.key_pad_PRO_UP = {0x0043, 0x0048, 0x0020, 0x0020, 0x0055, 0x0050, 0}，
.key_pad_PRO_DOWN = {0x0043, 0x0048, 0x0020, 0x0020, 0x0044, 0x004F, 0x0057, 0x004E,0}，
.key_pad_INPUT = {0x0049, 0x004E, 0x0050, 0x0055, 0x0054, 0}，
}；

，.key_pad_MENU[32]，
加下标是不是有点第32个元素的嫌疑？就像数组的复制一样，不可能第某个元素初始化4、5个值

我也认为是这样正确

static struct key_pad_vaule key_pad_button_vaule={

.key_pad_MENU = {0x004D, 0x0045, 0x004E, 0x0055, 0};

.key_pad_VOL_UP = {0x0056, 0x004F, 0x004C, 0x0020, 0x0055, 0x0050, 0};

.key_pad_VOL_DOWN = {0x0056, 0x004F, 0x004C, 0x0020, 0x0044, 0x004F, 0x0057, 0x004E,0};

.key_pad_PRO_UP = {0x0043, 0x0048, 0x0020, 0x0020, 0x0055, 0x0050, 0};

.key_pad_PRO_DOWN = {0x0043, 0x0048, 0x0020, 0x0020, 0x0044, 0x004F, 0x0057, 0x004E,0};

.key_pad_INPUT = {0x0049, 0x004E, 0x0050, 0x0055, 0x0054, 0};

};

{0x0049, 0x004E, 0x0050, 0x0055, 0x0054, 0}
};

{0x0049, 0x004E, 0x0050, 0x0055, 0x0054, 0}没有,结尾？

呵呵，看来1楼还没见识过C99的威力。

确实错了。你应该这么写：



static struct key_pad_vaule key_pad_button_vaule={

.key_pad_MENU = {0x004D, 0x0045, 0x004E, 0x0055, 0};

.key_pad_VOL_UP = {0x0056, 0x004F, 0x004C, 0x0020, 0x0055, 0x0050, 0};

.key_pad_VOL_DOWN = {0x0056, 0x004F, 0x004C, 0x0020, 0x0044, 0x004F, 0x0057, 0x004E,0};

.key_pad_PRO_UP = {0x0043, 0x0048, 0x0020, 0x0020, 0x0055, 0x0050, 0};

.key_pad_PRO_DOWN = {0x0043, 0x0048, 0x0020, 0x0020, 0x0044, 0x004F, 0x0057, 0x004E,0};

.key_pad_INPUT = {0x0049, 0x004E, 0x0050, 0x0055, 0x0054, 0};

};

想当然了

static struct key_pad_vaule key_pad_button_vaule={
{0x004D, 0x0045, 0x004E, 0x0055, 0},
{0x0056, 0x004F, 0x004C, 0x0020, 0x0055, 0x0050, 0},
{0x0056, 0x004F, 0x004C, 0x0020, 0x0044, 0x004F, 0x0057, 0x004E,0},
0x0043, 0x0048, 0x0020, 0x0020, 0x0055, 0x0050, 0},
{0x0043, 0x0048, 0x0020, 0x0020, 0x0044, 0x004F, 0x0057, 0x004E,0},
{0x0049, 0x004E, 0x0050, 0x0055, 0x0054, 0}
};
