C语言 结构体之时间设计&

解题思路:

注意事项:

参考代码:

#include <stdio.h>

struct calendar

{

     int year;

    int month;

    int day;

}date, * p;

int main()

{

         p = &date; int count=0;

         scanf_s("%d %d %d", &date.year, &date.month, &date.day);

         for (int i = 1; i < p->month; i++)

         {

                 if ((i % 2 != 0 && i < 8) || i == 8||i==10)//无需考虑12月

                 count = count + 31;

                 else if(i==2) count = count + 28;

                 else count = count + 30;

         }

         if (p->month>2&&(p->year% 400 == 0) || ((p->year % 4 == 0) &&( p->year % 100 != 0)) )

         count++;

         count = count + p->day;

         printf("%d", count);

         return 0;

}
