c语言指向结构体数组的指针

 #include <stdio.h>
 #include <stdlib.h>

 struct dangdang
 {
     char email[];
     char name[];
     char addr[];
     int num;
     int bugnum;
     char tel[];
     char phone[];
     double RMB;

 }dbdd[]={{"1171546435@qq.com","lj","重庆市",,,"","",},
 {"453454534@qq.com","fd","贵阳",,,"","",}
 };
 
//访问数组
 void main3()
 {
     int a[]={,,,,};
     int *p;
     for(p=a;p>a+;p++)//p++根据类型增加 一次增加四个字节
     {
         printf("%d%x",*p,p);
     }
 }

 void main4()
 {
     struct dangdang *p;
     for(p=dbdd;p<dbdd+;p++)
     {
         //两种方式
         printf("\nname=%s,addr=%s,phone=%s",p->name,p->addr,p->phone);
         printf("\nname=%s,addr=%s,phone=%s",(*p).name,(*p).addr,(*p).phone);
     }

     getchar();
 }
