typedef 结构体 简单例子

diaochenlong2

main()
{
typedef struct student
{
  int num,age;
  char name[20],sex,addr[30];
}Student,*STU;
Student s = {4102,26,"diaodiao",'M',"Beijing Road 11#"};
STU stu;
stu=&s;
printf("No.:%d\nName:%s\nSex:%c\nAddress:%s\n",s.num,s.name,s.sex,s.addr);
printf("No.:%d\nName:%s\nSex:%c\nAddress:%s\n",stu->num,stu->name,stu->sex,stu->addr);
}

typedef 原类型名 新类型名;

Student现在是结构体类型了
利用STU能定义结构体指针变量
