c - 枚举。找不到问题所在

Question

在头文件中:

  typedef struct apartment_t* Apartment;
  typedef enum { EMPTY, WALL } SquareType;

struct apartment_t {
    SquareType** squares;
    int width;
    int length;
    int price;
};

在源文件中:

int apartmentTotalArea(Apartment apartment) {

    int countEmpty = 0;

    for (int i=0;i<apartment->length;i++)
        for (int j=0;j<apartment->width;j++) {
            SquareType Square = apartment->squares[i][j];
            switch(Square) {
                case Square.EMPTY: // Bad
                    countEmpty++;
                    break;

                case Square.WALL: // Bad
                    break;
            }
        }

此函数计算给定二维数组中的空点。我在交换机中遇到问题，它会将这两种情况标记为错误的语句。我的代码有什么问题吗？谢谢。

您的代码中不存在 Square.EMPTY 或 Square.WALL 之类的内容。使用:

switch(Square) {
    case EMPTY:  // Juse EMPTY, not Square.EMPTY
        countEmpty++;
        break;

    case WALL:
        break;
}
