C语言程序设计教程（第三版）课后习题11.1 （C语言代码）

参考代码:

#include<stdio.h>

struct Date{
   int year;
   int month;
   int day;

   int leap;
   int count;
};

int main(void)
{
   struct Date date={0, 0, 0, 0, 0};
   
   scanf("%d %d %d", &date.year, &date.month, &date.day);
   
   if(date.year%400==0 || (date.year%100==0 && date.year%4==0)) date.leap = 1;
   
   int temp[] = {date.leap+date.day, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
   for(int i=0; i<date.month; i++) date.count += temp[i];

   printf("%d\n", date.count);
   
   return 0;
}
