[编程入门]结构体之时间设计-题解（C语言代码）

解题思路:

注意事项:

参考代码:

#include "stdio.h"

#include "stdlib.h"

int main (void)

{

     int x_day = 0;

     int dayvar=0,leapyear = 0;

     struct Date

     {

     int year;

     int month;

     int day;

     };

     struct Date str_date;

     scanf ("%d %d %d",&str_date.year,&str_date.month,&str_date.day);

     if ((((str_date.year%4)==0)&&((str_date.year%100)!=0)) || ((str_date.year%400)==0))

     {

     leapyear = 1;

     }

     dayvar = 1;

     while (1)

     {

         if (dayvar < str_date.month)

         {

                 if ((dayvar==1) || (dayvar==3) || (dayvar==5) || (dayvar==7) || (dayvar==8) || (dayvar==10) || (dayvar==12))

                 {

                      x_day += 31;

                 }

                 else if (dayvar == 2)

                 {

                     if (leapyear)

                     {

                          x_day += 29;

                     }

                     else

                     {

                          x_day += 28;

                     }

                 }

                 else

                 {

                     x_day += 30;

                 }

                 dayvar++;

             }

             else

             {

                  break;

             }

         }

     x_day += str_date.day;

     printf("%d\n",x_day);

     return 0;

}
