函数返回值

#include<stdio.h>
struct date{
int year;
int month;
int day;
} today={0,0,0};
struct date* get(struct date*);
int main()
{
struct date *p=&today;

get(&today);
printf("%d-%d-%d",p->year,p->month,p->day);
return 0;

 }
 struct date* get(struct date*p)
 {
     printf("请输入：");
scanf("%d %d %d",&p->year,&p->month,&p->day);
return p;
 }
问一下大佬们在get函数中我要输入两个p该怎样返回
