引入: 有时需要将不同类型的数据组合成一个有机的整体,以便于引用。 例如,一个学生有学号、姓名、性别、年龄、地址等属性,需要定义int num; char name[20]; char sex; int age; int char addr[30];等属性,如下:
registration::class_<Data>('Data') .constructor<int>() .method('Display', &Data::Display); } voidtest(){ type t = type::get_by_name('Data'); if(t.is_valid()) { std::cout<<'get methods: '<< t.get_method_count() <<std::endl; ...
enum color{red=4,green=1,blue,black}; 这条语句中从blue开始会自动往后递增,blue的值为2,black为3。 (09分50秒)※不能给枚举常量赋值,比如boy=2,这是错误的写法。 ※枚举常量相当于一个关键字,程序中不得出现与枚举常量相同的标识符。 ※枚举支持所有的逻辑运算,也可以递增递减,比如上面的枚举类型color值...
