//******************************************************************************
// 杭电2005 第几天？ 代码已AC
//******************************************************************************
#include<stdio.h> //标准C 头文件 ,AC时 Language选 C
int run(int x)
{
if ((x%4==0&&x%100!=0)||(x%400)==0)return 1;
else return 0;
}
int main()
{
int m[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};//依据后面代码，应该在前面添加一个 0
int days,i,sig,year,month,day;
while (scanf("%d/%d/%d",&year,&month,&day)!=EOF)
{
days=0;
sig=run(year);
for (i=1;i<month;i++) //***** i 是从1开始计数的 ，所以上面数组前面再加一个 0****
days+=m[i];
days+=day;
if (sig==1&&month>2)days++;
printf("%d\n",days);
}
return 0;

#include<cstdio>
int run(int x)
{
if((x%4==0&&x%100!=0)||(x%400)==0)return 1;
else return 0;
}
int main()
{
int m[13]={31,28,31,30,31,30,31,31,30,31,30,31};
int days,i,sig,year,month,day;
while(scanf("%d/%d/%d",&year,&month,&day)!=EOF)
{
days=0;
sig=run(year);
for(i=1;i<month;i++)
days+=m[i-1];//这里应该是m[i-1].你再试一下。
days+=day;
if(sig==1&&month>2)days++;
printf("%d\n",days);
}
return 0;
