有三个学生的信息(包括学号和成绩)保存在主函数的结构体中，主函数调用函数以找出多个学生中成绩最大者的下标。

#include <stdio.h>

struct Student
{
char No[11];
int Score;
};

int FindMaxScore(struct Student stu[], int n);

int main(void)
{
struct Student stus[3] = {{"2008030201", 89}, {"2008030202", 92}, {"2008030203", 78}};
int k;

3 分

printf("%s %d\n", stus[k].No, stus[k].Score);

return 0;

}

int FindMaxScore(3 分
)
{
int i, max, k=0;

max = stu[k].Score;    
for (i=1; i<n; i++)
{
    if (3 分

)
{
k = i;
max = stu[k].Score;
}
}

return k;

}

#include <stdio.h>

struct Student

    k = FindMaxScore(stus,3);

    printf("%s %d\n", stus[k].No, stus[k].Score);
