结构体数组与结构体数组指针

#include
#define num 3


struct date
{
    int day;
    int month;
    int year;
};

void input(struct date*);
void output(struct date*);

int main()
{
    struct date times[num];
    input(times);
    output(times);
}

void input(struct date*p)
{
    int i;
    for(i=0;i<num;i++)
    {
        printf("please enter the day%d:",i+1);
        scanf("%d",&(p+i)->day);
        printf("please enter the month%d:",i+1);
        scanf("%d",&(p+i)->month);
        printf("please enter the year%d:",i+1);
        scanf("%d",&(p+i)->year);
    }
}

void output(struct date*p)
{
    int i;
    for(i=0;i<num;i++)
    {
        printf("the %d date is %d %d %d\n",i+1,(p+i)->day,(p+i)->month,(p+i)->year);
    }
}

p指向struct[0],p+1指向struct[1]
