结构体中数组成员中内容的长度怎么求

电纸人

定义了一个汉字字模的结构体
struct typFNT_GB24                // 汉字字模数据结构
{
       unsigned char Index[2];            // 汉字内码索引
       char Msk[72];                      // 点阵码数据
};

struct typFNT_GB24  Label_Amount[] =   
{
"输", 0x08,0x02,0x00,0x0E,0x03,0x80,0x0C,0x07,
      0x00,0x0C,0x0E,0x80,0x19,0x0C,0x40,0x7F,
      0x98,0x30,0x18,0x31,0x98,0x30,0x4F,0xCE,
      0x36,0x80,0x04,0x36,0x23,0x10,0x36,0x3F,
      0x9C,0x7F,0xB3,0x58,0x26,0x33,0x58,0x06,
      0x3F,0x58,0x06,0x33,0x58,0x07,0xB3,0x58,
      0x1E,0x3F,0x58,0x76,0x33,0x58,0x26,0x33,
      0x58,0x06,0x33,0x18,0x06,0x33,0x18,0x06,
      0x37,0x18,0x06,0x22,0x78,0x04,0x00,0x30,

"入", 0x00,0x00,0x00,0x03,0x00,0x00,0x07,0xC0,
      0x00,0x00,0x30,0x00,0x00,0x10,0x00,0x00,
      0x08,0x00,0x00,0x18,0x00,0x00,0x1C,0x00,
      0x00,0x1C,0x00,0x00,0x34,0x00,0x00,0x32,
      0x00,0x00,0x62,0x00,0x00,0x63,0x00,0x00,
      0xC1,0x00,0x00,0xC1,0x80,0x01,0x81,0x80,
      0x03,0x00,0xC0,0x06,0x00,0xE0,0x0C,0x00,
      0x60,0x08,0x00,0x78,0x10,0x00,0x3E,0x20,
      0x00,0x18,0x40,0x00,0x00,0x00,0x00,0x00,

    …………
    …………
};

怎么计算 Label_Amount[]中字的个数呢？
这样会报错 length = sizeof(Label_Amount)/sizeof(struct  typFNT_GB24);

百度了一下，结构体声明放到.h中，也就是头文件当中。
你肯定将
struct typFNT_GB24                // 汉字字模数据结构
{
       unsigned char Index[2];            // 汉字内码索引
       char Msk[72];                      // 点阵码数据
};
放在.c中。

请问报什么错呢？

我试了下：
struct   abc              
{
u8 Index[2];                       
u8 Msk[24];                   

};

struct   abc GB_112[] =           // 数据表
{
    
"为", 0x00,0x08,0x10,0x08,0x12,0x04,0x1C,0x02,

      0x84,0x08,0x85,0x0F,0x86,0x08,0x94,0x08,

      0x12,0x08,0xF3,0x07,0x12,0x00,0x10,0x00,
  };


sizeof（结构体类型）为26。
sizeof（数组名）为234 = 26*汉字个数。

应该没有问题。

---------------------------------
 sizeof(Label_Amount)这句提示错误：incomplete type is not allowed

你提醒到我了 
struct typFNT_GB24                // 汉字字模数据结构 
{ 
       unsigned char Index[2];            // 汉字内码索引 
       char Msk[72];                      // 点阵码数据 
};
我定义在 .h文件中 而struct typFNT_GB24  Label_Amount[]定义在.c中的 所以会报错 解决了 谢谢
