PowerRecord  rcArray[POWER_RECORD_SEND_COUNT]=

             {0x0001,0x0002},
             {0x0001,0x0002},  
             {0x0001,0x0002},
             {0x0001,0x0002},
             {0x0001,0x0002},
             {0x0001,0x0002},
             {0x0001,0x0002},
             {0x0001,0x0002},
             {0x0001,0x0002},
             {0x0001,0x0002},            
};
unsigned char data[40];
int main(void)
{
   unsigned char i=0;
  memcpy(data,&rcArray,40);
  if(data[0]==0x00)
  printf("this is test right");
  else
  printf("this is test error");
  getchar();                                         
  return 0;  
}
为什么打印出来的是this is test error， memcpy为什么会出错。复制过去data【0】应该是0x00吧

打印出来是0

楼上说的不错，是小端格式了谢谢了给分了
