c语言学习之结构篇代码演示样例-输入n个同学的姓名，数学英语成绩，依照平均分从低到高排序并输出

#include<stdio.h>

void main(){

const int count = 5;//定义数量

struct student{

char name[80];

float math,eng;

float aver;

}stu[count],temp;

//输入

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

scanf("%s%f%f", stu[i].name, &stu[i].math, &stu[i].eng);

}

//将平均值放入进去

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

stu[i].aver = (stu[i].math + stu[i].eng )/ 2;

}

/*求平均分最高的同学姓名和平均分

int sub = 0;

for (int i = 1; i < 5; i++)

if (stu[i].aver>stu[sub].aver)sub = i;

printf("%s%f\n", stu[sub].name, stu[sub].aver);*/

/*依照平均分从低到高排序*/

for (int i = 0; i < count - 1; i++)

for (int j = 0; j < count - 1 - i; j++)

if (stu[j].aver>stu[j + 1].aver){

temp = stu[j];

stu[j] = stu[j + 1];

stu[j + 1] = temp;

}

//输出

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

printf("%s\t%f\t%f\t%f\n", stu[i].name, stu[i].math, stu[i].eng, stu[i].aver);

}

}
