C语言代码找错

#include <stdlib.h> /*使用m a l l o c ( ) 需要*/ struct data /*定义结构体*/ { int day,month,year; } ; struct stu /*定义结构体*/ { char name[20]; long num; struct data birthday; /*嵌套的结构体类型成员*/ } ; main() /*定义m a i n ( ... #include <stdlib.h> /*使用m a l l o c ( ) 需要*/
struct data /*定义结构体*/
{
int day,month,year;
} ;
struct stu /*定义结构体*/
{
char name[20];
long num;
struct data birthday; /*嵌套的结构体类型成员*/
} ;
main() /*定义m a i n ( ) 函数*/
{
struct stu *student; /*定义结构体类型指针*/
student=malloc(sizeof(struct stu)); /*为指针变量分配安全的地址*/
printf("Input name,number,year,month,day:\n");
scanf("%s",student->name); /*输入学生姓名、学号、出生年月日*/
scanf("%ld",student->num);
scanf("%d%d%d",student->birthday.year,student->birthday.month,
student->***.day);
printf("\nOutputname,number,year,month,day\n");/*打印输出各成员项的值*/
printf("%20s%10ld%10d//%d//%d\n",student->name,student->num,
student->birthday.year,student->birthday.month,
student->***.day);
}

不知道哪里错了，帮忙看一下 展开
