c语言中在结构体声明的时候不是需要初始化吗

[zjtzlqr]

typedef struct
{
 u8 box[2];
 u16 color;
 u8 next;
}Sha_Struct;


typedef struct
{
  u16 rdm;
  u16 posx,posy;
  Sha_Struct shapes[19]=
  {
   {0x88,0xc0,0x0,1},   //L
   {0xe8,0x0,0x0,2},
   {0xc4,0x40,0x0,3},
   {0x2e,0x0,0x0,0},

   {0x44,0xc0,0x1f,5},  //反L
   {0x8e,0x0,0x1f,6},
   {0xc8,0x80,0x1f,7},
   {0xe2,0x0,0x1f,4},

   {0x8c,0x40,0xf81f,9}, //反Z
   {0x6c,0x0,0xf81f,8},

   {0x4c,0x80,0xffe0,11}, //Z
   {0xc6,0x0,0xffe0,10},

   {0x4e,0x0,0x7ff,13},	  //凸
   {0x8c,0x80,0x7ff,14},
   {0xe4,0x0,0x7ff,15},
   {0x4c,0x40,0x7ff,12},

   {0x88,0x88,0xf800,17},  //长条
   {0xf0,0x0,0xf800,16},

   {0xcc,0x0,0xf81f,18} //立方体
  };  
}Tet_Struct;

首先声明了一个结构体Sha_Struct，然后另外一个结构体里面声明了一个结构体组Sha_Struct shapes[19]=
但是为什么编译器说这里有错误，expected a ";" 到底是为什么呢？

[AnYidan]

可能是此句 （前）有未定义的 类型 或 变量

[zjtzlqr]

但是没有看到有未定义的类型或者变量啊

[yzlovme]

结构体申明的时候是不需要初始化的

[zhuyf87]

typedef在定义新类型的时候，直接对struct成员进行初始化？没这么用过。 不清楚标准支不支持，楼主是什么编译器。 我觉得像9楼那样，用的“正常”点挺好。

[rocktyt]

expected a ";"这句错误在哪一行呢

[zjtzlqr]

引用 3 楼 rocktyt2 的回复:

expected a ";"这句错误在哪一行呢

在第13行

[rocktyt]

{0x88,0xc0,0x0,1}, 改成 {{0x88,0xc0},0x0,1}, box也是数组 这样试试

无代码 无真相

[赵4老师]

偶遇到类似问题都是用 “每次用/*...*/注释掉不同部分再重新编译，直到定位到具体语法出错的位置。” 的方法解决的。

楼主这样定义结构体是不对的，第二个结构体还是在声明，不能在声明结构体中初始化； 参考下下面的声明、定义和初始化；

typedef struct
{
 u8 box[2];
 u16 color;
 u8 next;
}Sha_Struct;
 
 
typedef struct
{
  u16 rdm;
  u16 posx,posy;
  Sha_Struct shapes[19];
}Tet_Struct;

Tet_Struct tmp = 
{
    20,   //初始化rdm
    20,   //初始化posx
    20,   //初始化posy
  {       //初始化shapes
   {0x88,0xc0,0x0,1},   //L
   {0xe8,0x0,0x0,2},
   {0xc4,0x40,0x0,3},
   {0x2e,0x0,0x0,0},
 
   {0x44,0xc0,0x1f,5},  //反L
   {0x8e,0x0,0x1f,6},
   {0xc8,0x80,0x1f,7},
   {0xe2,0x0,0x1f,4},
 
   {0x8c,0x40,0xf81f,9}, //反Z
   {0x6c,0x0,0xf81f,8},
 
   {0x4c,0x80,0xffe0,11}, //Z
   {0xc6,0x0,0xffe0,10},
 
   {0x4e,0x0,0x7ff,13},      //凸
   {0x8c,0x80,0x7ff,14},
   {0xe4,0x0,0x7ff,15},
   {0x4c,0x40,0x7ff,12},
 
   {0x88,0x88,0xf800,17},  //长条
   {0xf0,0x0,0xf800,16},
 
   {0xcc,0x0,0xf81f,18} //立方体
  };  
}
