2016徵求年菜推薦網路訂購最紅的商家.年菜訂購?台北年菜外送餐廳推薦(年菜)?年菜.今年不想做年菜推薦,網路宅配哪一家好?

(1) 使用 struct mydata：
11 行是以 mydata 宣告了 customer 變數
12 行應該就出錯了

12, 13 改為
struct mydata *ftp;
ftp=( struct mydata *)calloc(10,sizeof( struct mydata));

(2) 使用 typedef：
由於 C struct 要連帶 struct ，使用上很麻煩。大多會用 typedef 將 struct tagName 定義新 type。

也就是在第 3 行，加上 typedef，而 customer 成為新 type name，等義於 struct mydata。

int main(void)
{
typedef struct mydata
{
char name[25];
char Address1[30];
char Address2[30];
int order;
char type;
char risk;
} customer;
customer *ftp;
ftp=(customer*)calloc(10,sizeof(customer));
return 1;
}
