Question

设计一个学生类Stu,包括学生姓名、成绩（char*name;double score），并求出下列一组学生：{Stu（“zhang”,

78），Stu（“wang”,80）,Stu("zhao",92),Stu("li",65),Stu("chen",50)}中的最高分和最低分

Answer 1

#include<stdio.h>
struct Stu
{
char name[10];
float score;
}student[5]={{"zhang",78},{"wang",80},{"zhao",92},{"li",65},{"chen",50}};
int highscore(struct Stu *pst)
{
struct Stu stu;
int i,j;
stu=pst[0];
for(i=0;i<5;i++)
{
if(pst[i].score>stu.score)
{
stu=pst[i];j=i;
}
}
return j;

}
int lowscore(struct Stu *pst)
{
struct Stu stu;
int i,j;
stu=pst[0];
for(i=0;i<5;i++)
{
if(pst[i].score<stu.score)
{
stu=pst[i];j=i;
}
}
return j;

}

void main()
{

int lowindex,highindex;
lowindex=lowscore(student);
highindex=highscore(student);
printf("最高分是%s,分数：%.2f\n",student[highindex].name,student[highindex].score);
printf("最低分是%s,分数：%.2f\n",student[lowindex].name,student[lowindex].score);

}
调试过了，可以出结果
