Chapter 7. 结构体、枚举

//结构体：定义一组变量
        struct student
        {
            public int number;
            public string name;
            public string sex;
            public one xx;
            
        }
        struct one
        {
            public string aa;
            public int bb;
        }

        //枚举类型：定义一个常量
        enum meiju
        {
            one = 3, //不是赋值，是指向索引，3号索引是one
            two = 6, //6号索引是two这个常量
            three,
            four = two  //逗号可以省略，若一个常量等于之前的一个常量，那么就等于这个常量
        }
        enum meiju1
        {
            one = 3,
            two = 6,
            three,
            four = three
        }


        static void Main(string[] args)
        {
            //初始化结构体
            student stu = new student();
            stu.number = 1;
            stu.name = "张三";
            stu.sex = "男";
