Question

我有一项任务要求我生成一个10乘10的网格，每个网格都是空的或用星号填充。启动代码包括它应该生成的模式，但我只是不确定如何处理它。

在帮助文件中，声明了此typedef

#define BOARD_WIDTH 10
#define BOARD_HEIGHT 10

typedef enum cell{
    EMPTY,
    BLOCKED,
    PLAYER
} Cell;

#define EMPTY_OUTPUT " "
#define BLOCKED_OUTPUT "*"

Cell BOARD_1[BOARD_HEIGHT][BOARD_WIDTH];
Cell BOARD_2[BOARD_HEIGHT][BOARD_WIDTH];

这是c文件中的代码

Cell BOARD_1[BOARD_HEIGHT][BOARD_WIDTH] =
{
    { BLOCKED, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY },
    { EMPTY, BLOCKED, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, BLOCKED, EMPTY, EMPTY },
    { EMPTY, EMPTY, BLOCKED, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY },
    { EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, BLOCKED, EMPTY, EMPTY },
    { EMPTY, EMPTY, EMPTY, EMPTY, BLOCKED, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY },
    { EMPTY, EMPTY, BLOCKED, EMPTY, EMPTY, BLOCKED, EMPTY, BLOCKED, EMPTY, EMPTY },
    { EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, BLOCKED, EMPTY, EMPTY, EMPTY },
    { EMPTY, EMPTY, BLOCKED, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY },
    { EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY },
    { EMPTY, EMPTY, BLOCKED, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, BLOCKED }
};

我写了一些代码来生成一个空白网格

void initialiseBoard(Cell board[BOARD_HEIGHT][BOARD_WIDTH])
{
int x;
int y;
printf("| |");
for(x=0; x<=9; x++){
    printf("%i|", x);
}
printf("\n");
for (y=0; y<=9; y++){

    printf("|%i|", y);
    for(x=0; x<=9; x++){
        printf(" |");
    }
    printf("\n");
}

}
void loadBoard(Cell board[BOARD_HEIGHT][BOARD_WIDTH],
           Cell boardToLoad[BOARD_HEIGHT][BOARD_WIDTH])
{
    /* TODO */
}

但我不确定如何使用BOARD_1单元格用星号填充网格。这个函数initialiseBoard()也是启动代码的一部分，我还想解释为什么在生成空白网格时需要参数。

“生成”并不意味着“打印到标准输出”，它意味着“创建内存状态”，换句话说，您的initialiseBoard()函数应该更改内容它通过的板阵列，使它成为一个初始化的板（而不是一个随机的非初始化板）。

循环中的printf()应该是board的单元格的分配：

void initialiseBoard(Cell board[BOARD_HEIGHT][BOARD_WIDTH])
{
  for (size_t y = 0; y < BOARD_HEIGHT; ++y)
  {
    for (size_t x = 0; x < BOARD_WIDTH; ++x)
      board[y][x] = EMPTY;
  }
}

这会将所有单元格设置为EMPTY。

我该如何处理这个typedef？
