[编程入门]结构体之成绩统计2-题解（C语言代码）

解题思路:

注意事项:

参考代码:

#include"stdio.h"

#include<math.h>

#include<stdlib.h>

#include<string.h>

struct student

{

    char sno[20];

    char name[20];

    int grade1;

    int grade2;

    int grade3;

};

void input(struct student a[])//进行输入

{

    scanf("%s %s %d %d %d",a->sno,a->name,&(a->grade1),&(a->grade2),&(a->grade3));

}

void output(struct student a[],int sum1,int sum2,int sum3,int n)//进行输出

{

    printf("%d %d %d",sum1/n,sum2/n,sum3/n);

    printf("\n");

    printf("%s %s %d %d %d",a->sno,a->name,(a->grade1),(a->grade2),(a->grade3));

}

int main()

{

    int n;

    scanf("%d",&n);

    struct student s[n];

    for(int i = 0;i < n;i++)

    {

        input(&s[i]);

    }

    int sum1 = 0,sum2 = 0,sum3 = 0;

    int t = 0,maxx = 0;

    for(int i = 0;i < n;i++)

    {

        sum1 = sum1+s[i].grade1;

        sum2 = sum2+s[i].grade2;

        sum3 = sum3+s[i].grade3;

        if((s[i].grade1+s[i].grade2+s[i].grade3)>maxx)

        {

            maxx = s[i].grade1+s[i].grade2+s[i].grade3;

            t = i;

        }

    }

     output(&s[t],sum1,sum2,sum3,n);

    return 0;
