7、-1;i+) k=i; for(j=i+1;j<n;j+) if(stuj.score>stuk.score) k=j; temp=stuk; stuk=stui; stui=temp; for(i=0;i<n;i+) printf("%6d %8s %6.2fn", stui.num,,stui.score); printf("n"); return 0;5、通過指向結(jié)構(gòu)體變量的指針變量輸出結(jié)構(gòu)體變量中成員的信息。#include <stdio.h>#include <string.h>int

8、 main() struct Student long num; char name20; char sex; float score; ;struct Student stu_1; struct Student * p; p=&stu_1; stu_1.num=10101; strcpy(stu_1.name,“Li Lin”); stu_1.sex='M; stu_1.score=89.5; printf("No.:%ldn”,p->.num); printf("name:%sn", p->.name); printf("

9、sex:%cn”, p->.sex); printf(”score:%5.1fn”,stu_1.score); return 0;6、有3個學(xué)生的信息，放在結(jié)構(gòu)體數(shù)組中，要求輸出全部學(xué)生的信息。#include <stdio.h>struct Student int num; char name20;char sex; int age;struct Student stu3=10101,"Li Lin",'M',18,10102,"Zhang Fun",'M',19,10104,"Wang Mi

10、n",'F',20 ;int main() struct Student *p; printf(" No. Name sex agen"); for(p=stu;p<stu+3;p+) printf(“%5d %-20s %2c %4dn”,p->num, p->name, p->sex, p->age); return 0;7、有n個結(jié)構(gòu)體變量，內(nèi)含學(xué)生學(xué)號、姓名和3門課程的成績。要求輸出平均成績最高的學(xué)生的信息(包括學(xué)號、姓名、3門課程成績和平均成績)。#include <stdio.h>#define

11、 N 3struct Student int num; char name20; float score3; float aver; ;int main() void input(struct Student stu); struct Student max(struct Student stu); void print(struct Student stu); struct Student stuN; input(stu); print(max(stu); return 0;void input(struct Student stu) int i; printf("請輸入各學(xué)生的信

12、息：學(xué)號、姓名、三門課成績:n"); for(i=0;i<N;i+) scanf("%d %s %f %f %f",&stui.num,,&stui.score0,&stui.score1,&stui.score2); stui.aver=(stui.score0+stui.score1+stui.score2)/3.0; struct Student max(struct Student stu) int i,m=0; for(i=0;i<N;i+) if (stui.aver>stum.ave

13、r) m=i; return stum; void print(struct Student stud) printf("n成績最高的學(xué)生是:n");printf("學(xué)號:%dn姓名:%sn三門課成績:%5.1f,%5.1f,%5.1fn平均成績:%6.2fn",stud.num,,stud.score0,stud.score1,stud.score2,stud.aver); 8、有若干個人員的數(shù)據(jù)，其中有學(xué)生和教師。學(xué)生的數(shù)據(jù)中包括：姓名、號碼、性別、職業(yè)、班級。教師的數(shù)據(jù)包括：姓名、號碼、性別、職業(yè)、職務(wù)。要求用同一個表格來處理。#
