#include<stdlib.h>
struct date {
int year;
int month;
int day;
};
struct student {
long int no;
char name[20];
struct date birthday;
unsigned sex;
float score;
};
struct student mstd[3] = {//std是C++的命名空间名称，这里改为mstd。要说明的是，假如你使用标准C编译环境就没有命名冲突了，若使用C++环境则会报错。
{2013160123,"ZHANG San",1997,7,21,0,90.00},{2013160124,"LI Si",1998,8,21,1,92.00},
{2013160125,"WANG Wu",1999,2,21,0,93.00}
};
int main() {
int i;
long no;
printf("please input no:\n");
scanf("%ld",&no);
for (i = 0;i < 3;i++)
