若有下列定义，则对结构体变量的成员引用错误的是( )。struct date { int year; int month; int day;}struct student{int no;char name[16];date birthday;}stud; A: stud.no B: stud.name C: stud.birthday D: stud.birthday.year

在stud表中返回年龄最小的8位同学的信息，使用（)。 A: A.SELECT * FROM stud ORDER BY birthday DESC LIMIT 8; B: B.SELECT * FROM stud ORDER BY birthday ASC LIMIT 8; C: C.SELECT * FROM stud ORDER BY birthday ASC LIMIT 7; D: D.SELECT * FROM stud ORDER BY birthday DESC LIMIT 7;

从datetime类型的数据列 birthday 中获取年份，正确 的方法是： A: frame['birthday'].dt.year B: frame['birthday'].year C: datetime.now().year D: pd.to_datetime(frame['birthday'])

程序：class Birthday{int year;int month;int day;public Birthday(int year,int month,int day){year = year; month = month; day = day;}public static void main(String[] args){Birthday birth = new Birthday(1980,10,22); System.out.println(year);}}程序运行后的输出是哪项？ A: 1980 B: 10 C: 22 D: 0 E: 编译出错

在SELECT语句中,与排序有关的关键字是______。 A: ORDER BY B: LIMIT C: DESC D: ASC E: ： ACD F: 、查询1997,1999年出生的同学信息,正确的SELECT语句是______。 G: SELECT * FROM student WHERE YEAR(birthday) NOT IN(1997,1999); H: SELECT * FROM student WHERE YEAR(birthday)=1997 OR YEAR(birthday)=1999; I: SELECT * FROM student WHERE YEAR(birthday) IN(1997,1999); J: SELECT * FROM student WHERE YEAR(birthday) EXISTS(1997,1999);

Happy birthday! By this time of next year, you _________ (turn) 18.

定义如下结构体来描述一个人的基本情况： struct date {int year; int month; int day; }; struct person {char name[20]; char sex; struct date birthday; }man;如果某人的生日是1988年10月9日，下列对生日的正确赋值是 。 A: man·birthday·year=1988 man·birthday·.month=10 man·birthday·day=9 B: birthday·year=1988birthday·month=10birthday·day=9 C: man·year=1988man·month=10man·day=9 D: year=1988 month=10 day=9

在stud表中返回年龄最小的8位同学的信息，使用（ ） A: SELECT * FROM studORDER BY birthday DESCLIMIT 8; B: SELECT * FROM studORDER BY birthday ASCLIMIT 8; C: SELECT * FROM studORDER BY birthday ASCLIMIT 7; D: SELECT * FROM studORDER BY birthday DESCLIMIT 7;

假设有如下结构类型及结构变量: struct SDate { int year; int month; int day; } birthday; struct SDate *p = &amp;birthday;<br/>则通过指针p给它指向的结构的year成员赋值为2025的语句是( ) A: p.year = 2025; B: p-&gt;year = 2025; C: (*p)-&gt;year = 2025; D: *(p-&gt;year) = 2025;

---Happy New Year! A: It's OK B: Yes. C: The same to you. D: Happy birthday!
