计算天数

判断是平年或闰年的方法：if(year%100!=0 && year%4==0 || year%400==0)

代码如下：

//可以将每个月的天数保存在数组中 
#include<iostream>
using namespace std;
int main()
{
	int year_y[12]={31,29,31,30,31,30,31,31,30,31,30,31};
	int year_n[12]={31,28,31,30,31,30,31,31,30,31,30,31};
	int m;
	cin>>m;
	while(m--)
	{
		int year,month,day;
		cin>>year>>month>>day;
		
		int *Year;//
		 
		if(year%100!=0&&year%4==0 || year%400==0)
			Year=year_y;
		else Year=year_n;
		int i,num=0;
		for(i=0;i<month-1;i++)
			num+=Year[i];
		num+=day;
		cout<<num<<"\n";
	}
	return 0;
}
