大神们结构指针问题！给看看

程序代码：

#include<stdio.h>
#include<stdlib.h>
int main()
{  

 int i;
typedef struct
   {
     char xing[20];
     char ming[20];
   }xing_ming;
   xing_ming jie_zuo_zhe;
  
   typedef struct
   {
     char shu_ming[40];
     xing_ming jie_zuo_zhe;
     float jia_ge;    
   }book;
  
   book *zhi_book[3];//定义指向book结构的指针数组；
  
   for(i=0;i<3;i++)
   {
       zhi_book[i]=(book *)malloc(sizeof(book));
   puts("请输入书籍名！");
   gets(zhi_book[i]->shu_ming);
   puts("请输入作者的姓名！");
   scanf("%s%s",zhi_book[i]->jie_zuo_zhe.xing,zhi_book[i]->jie_zuo_zhe.ming);
   puts("请输入书籍的价格！");
   scanf("%f",zhi_book[i]->jia_ge);
   while(getchar()!='\n')
   continue;
   free(zhi_book[i]);
   }
   for(i=0;i<3;i++)
   printf("书籍的名称：%10s 书籍的作者：%6s%6s 书籍的价格：%10g\n",
   zhi_book[i]->shu_ming,zhi_book[i]->jie_zuo_zhe.xing,zhi_book[i]->jie_zuo_zhe.ming,
   zhi_book[i]->jia_ge);  
}

程序运行输入完价格程序就出错了！不知道怎么回事
