[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>

typedef struct{

    int year,month,date;

}time;

int sum(int year, int month, int date)

{

    int num[12]={31,28,31,30,31,30,31,31,30,31,30,31};

    int sn=0;

    for(int i=0; i<month-1; i++)

    {

        sn += num[i];

    }

    sn += date;

    if(year%400==0 && month>2) sn += 1;

    return sn;

}

int main()

{

    time days;

    int day;//该年第几天

    scanf("%d %d %d", &days.year, &days.month, &days.date);

    day=sum(days.year,days.month,days.date);

    printf("%d\n", day);

    return 0;

}
