學習目標：

1. 掌握枚舉類型的使用方法。

 

示例代碼：

#include <stdio.h>
#include <string.h>

        white,
        black,
        blue,

    if (strcmp(in_color, "white") == 0) {

    } else if (strcmp(in_color, "black") == 0) {
        my_color = black;
    } else if (strcmp(in_color, "blue") == 0) {
        my_color = blue;
    } else if (strcmp(in_color, "red") == 0) {
        my_color = red;
    } else {
        my_color = other;
    }

    printf("first >> %s: %d\n", in_color, my_color);
}

    } else if (strcmp(in_color, "red") == 0) {

    }

    printf("fourth >> %s: %d\n", in_color, my_color);

}
