//结构体
struct da
{
int num;//PS: 学号
char name[10];//PS: 姓名
float score[3]; //PS: 成绩
};
int i;//基本数据类型
int d[10];
struct da data;
int main()
{
struct da d1= {45,"hjhj",{77,88,99}};//定义的一个空间 (一个struct类型数组）
d1.num = 888;
d1.score[1] = 99.8f//给某一块区域赋值
int i=d1.num;

1、/*
1、找出第三个同学的姓名和学号
*/
#include<stdio.h>
struct student
{
int num;
char name[10];
};
int main()
{
test1();
}
void test1()
{
struct student s[5]={1,"w2",12,"z3",3,"14",4,"d1",5,"q3"};
printf("%s %d",s[2].name,s[2].num);
}
2、//2、找出学号为12的同学姓名，输出%s，数组名
#include<stdio.h>
struct student
{
int num;
char name[10];
};
struct student s[5]={1,"w2",12,"z3",3,"14",4,"d1",5,"q3"};

{
test1();
}
void test1()
{
printf("%s %d",s[2].name,s[2].num);
}
void find()
{

for(i=0;i<5;i++)
{

printf("%s",s[i].name);
}
}
