Expected ' ' in definition of struct-CodePudding

I'm working on a school project right now and i need to define two structs as addresses, like the code below shows :

typedef struct board_t* board;
/**
 * @brief Pointer to the structure that holds the game.
 */

typedef struct piece_t* piece;
/**
 * @brief Pointer to the structure that holds a piece
 */

and if i let it like it, it compiles. However, as soon as I try replacing the semicolon by a bracket to define the struct, I get a compilation error. Here's the code and the error :

typedef struct piece_t* piece{
/**
 * @brief Pointer to the structure that holds a piece
 */
 enum shape p_shape;
 enum size p_size;
 enum color p_color;
 enum top p_top;
 enum players author;
};


typedef struct board_t* board{
/**
 * @brief Pointer to the structure that holds the game.
 */
 piece array[4][4];
}

And the error :

error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘{’ token
   53 | typedef struct board_t* board{

What i need to do is create a board filled with pieces that i can edit inside functions. Can anyone help me?

CodePudding user response：

I think typedef names need to be at the end

typedef struct piece_struct {
/**
 * @brief Pointer to the structure that holds a piece
 */
 enum shape p_shape;
 enum size p_size;
 enum color p_color;
 enum top p_top;
 enum players author;
}
piece;


typedef struct board_struct {
/**
 * @brief Pointer to the structure that holds the game.
 */
 piece array[4][4];
}
board;

and if you want a typedef name for the pointer, you would need to create those separately.

typedef piece* piece_ptr;
typedef board* board_ptr;

Perhaps the code is clearer if the structure definitions are separated from the typedefs:

struct piece_struct {
/**
 * @brief structure that holds a piece
 */
 enum shape p_shape;
 enum size p_size;
 enum color p_color;
 enum top p_top;
 enum players author;
};

typedef piece_str* piece;  // piece is a new name for a pointer
                           // to a piece_str

struct board_struct {
/**
 * @brief structure that holds the game.
 */
 piece array[4][4];
};

typedef struct board_struct* board;   // board is a new name for a pointer
                                      // to a board_str

Personally I tend not to make typedefs for pointers as I find it difficult to remember whether it is a pointer or the struct itself, so I make a typedef for the struct and use * when declaring a pointer.
