#include <iostream>                                                                  
using namespace std;                                                                      
struct ENTINFO {                                                                          
  char ent_add[255];                                                                      
};                                                                                        
typedef struct ENTINFO _ENTINFO;                                        
int main(int argc, char *argv[])                                                          
{                                                                                                                                                
  _ENTINFO *ent_info_pointer;                                                              
  _ENTINFO ent_info[1024];                                                                
  memset(ent_info,0,sizeof(_ENTINFO)*1024);                                                
  strcpy(ent_info[0].ent_add,"guangdong shenzhen nanshan new haofang garden");            
  strcpy(ent_info[1].ent_add,"guangdong shenzhen nanshan haofang garden");                
  strcpy(ent_info[2].ent_add,"guangdong shenzhen nanshan haofang garden 6 floor");          
  ent_info_pointer = ent_info;                                                            
  printf("ent_info_pointer->ent_add=%s\n",ent_info[0].ent_add);                            
  printf("ent_info_pointer->ent_add=%s\n",ent_info[1].ent_add);                            
  printf("ent_info_pointer->ent_add=%s\n",ent_info[2].ent_add);                            
  printf("ent_info_pointer->ent_add=%s\n",ent_info_pointer->ent_add);                      
  ent_info_pointer++;                                                                      
  printf("ent_info_pointer->ent_add=%s\n",ent_info_pointer->ent_add);                      
  ent_info_pointer++;                                                                      
  printf("ent_info_pointer->ent_add=%s\n",ent_info_pointer->ent_add);                      
  return 0;                                                                                
}
                                                                                        
                                                                                          

运行结果:
ent_info_pointer->ent_add=guangdong shenzhen nanshan new haofang garden
ent_info_pointer->ent_add=guangdong shenzhen nanshan haofang garden
ent_info_pointer->ent_add=guangdong shenzhen nanshan haofang garden 6 floor
ent_info_pointer->ent_add=guangdong shenzhen nanshan new haofang garden
ent_info_pointer->ent_add=guangdong shenzhen nanshan haofang garden
ent_info_pointer->ent_add=guangdong shenzhen nanshan haofang garden 6 floor
