一、不定项选择题
1、B C错是因为编译后还需要链接，D函数可以单独编译，编译成目标文件
2、
3、D
4、CD
5、
6、B
7、
（1）C

5、AB,B
三、数据库
create table S(
Sno int primary key auto_increment,
Sname varchar(20)
);
insert into S(sname) values(‘he‘);
insert into S(sname) values(‘wang‘);
create table C(
Cno int primary key auto_increment,
Cname varchar(20),
Ccredit int
);
insert into C(cname,Ccredit) values(‘JAVA‘,3);
insert into C(cname,Ccredit) values(‘C‘,2);
Drop table if exists SC;
create table SC(
id int primary key auto_increment,
Sno int,
Cno int,
Grade int
);
insert into SC(Sno,cno,Grade) values(1,1,100);
insert into SC(Sno,cno,Grade) values(1,2,90);
insert into SC(Sno,cno,Grade) values(2,1,80);
insert into SC(Sno,cno,Grade) values(2,2,70);
insert into SC(Sno,cno,Grade,Teacher) values(3,1,80,‘zhang‘);
insert into SC(Sno,cno,Grade,Teacher) values(3,2,70,‘zhang‘);
1)select distinct Sname From S,SC,C where S.sno = SC.sno and c.Cno = SC.cno and
Cname=‘JAVA‘ order by Sname desc;
2)select S.Sno,Sum(Ccredit) From S,SC,C where S.sno = SC.sno and c.Cno = SC.cno
and Grade>60 group by Sno having sum(Ccredit)>80;
3)ALTER table SC ADD Teacher varchar(20) not null;
4)CREATE VIEW SCSum(sno,Ccredit) as Select S.Sno,Sum(Ccredit) From S,SC,C
where S.sno = SC.sno and c.Cno = SC.cno group by Sno;
5)delete from SC where sno not in(select distinct S.Sno from S);
四、编程题
1、
package hengsheng; import java.util.Scanner; public class Exe3 { public static void main(String[] args) { Date date = new Date(2015,8,25); System.out.println(days(date)); } static int days(Date date){ int day = 0; int[][] month = new int[][]{{31,28,30,31,30,31,31,31,30,31,30,31},{31,29,30,31,30,31,31,31,30,31,30,31}}; int m = isrunYear(date.getYear()); for(int i=0;i<date.getMonth()-1;i++){ day += month[m][i]; } day += date.getDay(); return day; } static int isrunYear(int year) { if (year % 4 == 0 && year % 100 != 0 | year % 400 == 0) return 0; return 1; } } class Date { int year; int month; int day; public Date(int year, int month, int day) { super(); this.year = year; this.month = month; this.day = day; } public int getYear() { return year; } public void setYear(int year) { this.year = year; } public int getMonth() { return month; } public void setMonth(int month) { this.month = month; } public int getDay() { return day; } public void setDay(int day) { this.day = day; } }
2、
package hengsheng; import java.util.Scanner; public class Exe2 { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int n = scanner.nextInt(); while (n != 1) { for (int i = 2; i<=n; i++) { if (isPrime(i)) { // 如果i为素数 if (n % i == 0) { // 如果n能被i整数 n = n / i; System.out.print(i + " "); break; } } } } } /** * 判断是否是素数 * * @param num * @return */ static boolean isPrime(int num) { for (int i = 2; i <= num / 2; i++) if (num % i == 0) return false; return true; } }
