题目：编写一个print函数，打印5个学生的数据记录。每个记录包括num,name,score.

#include <stdio.h>

struct student
{
 char  num[7];
 char  name[20];
 float  score;
};

struct student data[5]={
 {"0124301","hanjia",99.5},
 {"0124302","hanbaogang",98.5},
 {"0124303","gaobo",95},
 {"0124304","huwei",99},
 {"0124305","wangyu",98},
 };

//打印学生数据记录
void print(struct student a[5])
{
 int i;
 for(i=0;i<5;i++)
  printf("%s-%s-%3.1f\n",a[i].num,a[i].name,a[i].score);
}

main()
{
 print(data);
 //getch();
}

编译后的运行结果是：

 0124301hanjia－hanjia－99.5

 0124302hanbaogang－hanbaogang－98.5

 0124303gaobo－gaobo－95

 0124304huwei－huwei－99

 0124305wangyu－wangyu－98

为什么name会输出两次呢？不解！
