帮忙看一个C程序，结果不如自己所想

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！
