结构硬编码初始化中的C结构

Question

我在C99做错了什么:

struct chess {
    struct coordinate {
        char piece;
        int alive;
    } pos[3];
}table[3] =
{
    {
      {'Q', (int)1},{'Q', (int)1},{'Q', (int)1},
      {'B', (int)1},{'B', (int)1},{'B', (int)1},
      {'K', (int)1},{'K', (int)1},{'K', (int)1},
    }
};

它给出了错误:

error: expected ‘:’, ‘,’, ‘;’, ‘}’ or ‘__attribute__’ before ‘=’ token

我希望能够访问数据,例如在结构中具有结构:

table[row].pos[column].piece
table[row].pos[column].alive

我尝试了几种组合,似乎没有一种组合适用于这种情况.在此之前我已经完成了之前的struct硬编码初始化,但这次不是结构中的结构.

有什么建议？

尝试将char文字括在单引号中,如上所述,并添加额外的大括号,使内部数组成为初始化列表.

struct chess
{
   struct coordinate
   {
       char piece;
       int alive;
   } pos[3];
}
table[3] =
{  // table of 3 struct chess instances...
   { // ... start of a struct chess with a single member of coordinate[3]...
      { // ... this is where the  coordinate[3] array starts... 
         // ... and those are the individual elements of the  coordinate[3] array
         {'Q', 1}, {'Q', 1}, {'Q', 1}
       }
    },
    {{{'B', 1}, {'B', 1}, {'B', 1}}},
    {{{'K', 1}, {'K', 1}, {'K', 1}}}
};
