莉露C语言编写题解 1051: [编程入门]结构体之成绩统计2

解题思路:
如下
注意事项:
大爷的，题目没说平均分保留几位小数，测试了才知道int就行。
参考代码:

#include<stdio.h>

#include<string.h>

typedef struct Student{

char id[10];

char name[30];

int score[3];

}Stu;

int main(){

int N;

scanf("%d",&N);

Stu stu[102];

int sum[102];

int best = -1;

int bestp;

int a = 0;

int b = 0;

int c = 0;

for(int i=0;i<N;i++){

scanf("%s %s %d %d %d",stu[i].id,stu[i].name,&stu[i].score[0],&stu[i].score[1],&stu[i].score[2]);

a += stu[i].score[0];

b += stu[i].score[1];

c += stu[i].score[2];

sum[i] = stu[i].score[0]+stu[i].score[1]+stu[i].score[2];

if (sum[i] > best){

bestp = i;

best = sum[i];

}

}

int avg1;

avg1 = a/N;

int avg2;

avg2 = b/N;

int avg3;

avg3 = c/N;

printf("%d %d %d\n",avg1,avg2,avg3);

printf("%s %s %d %d %d\n",stu[bestp].id,stu[bestp].name,stu[bestp].score[0],stu[bestp].score[1],stu[bestp].score[2]);

return 0;

}
