结构体变量统计天数
定义一个结构体变量（包括年月日）。计算该日在本年中是第几天
#include<iostream>
using namespace std;
struct date
{
int year;
int month;
int day;
};
int main()
{
date x;
int days=0,i;
int Days[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};
cin>>x.year>>x.month >>x.day;
for(i=1;i<x.month;i++)
{
days+=Days[i];
}
days=days+x.day;
if(x.month>2)
{
if((x.year%4==0&&x.year%100!=0)||x.year%400==0)
{
days=days+1;
}
}
cout<<days;
return 0;
}
using namespace std;
struct date
{
int year;
int month;
int day;
};
int main()
{
date x;
int days=0,i;
int Days[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};

if(x.month>2)
{
if((x.year%4==0&&x.year%100!=0)||x.year%400==0)
{

}
}
cout<<days;
return 0;
}
