[编程入门]结构体之时间设计（C语言代码）简单易懂

解题思路:

注意事项:

参考代码:

#include <stdio.h>

struct date

{

    int year;

    int month;

    int day;

};

int Nowday(struct date Date)

{

    int sum = 0;

    int i;

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

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

    {

        a[1] = 29;

    }

    for(i = 0; i < Date.month - 1; i++)

    {

        sum += a[i];

    }

    sum += Date.day;

    return sum;

}

int main()

{

    struct date nowdate;

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

    printf("%d", Nowday(nowdate));

    return 0;

}
