一个一年中第几天的算法
#include <stdio.h>
int main()
{
    int day,year,month,i;
    int daymonth[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};
    if (year%4==0&&year%100!=0||year%400==0)
    {
        daymonth[2]=29;
    }
    while(scanf("%d/%d/%d",&year,&month,&day))
    {
        for(i=0;i<month;i++)
        day+=daymonth[i];
        printf("%d",day);
        printf("\n");
    }
    return 0;
}
怎么不对？？2006/3/12应该输出71，而我输出了72，怎么回事呢，请高手指点

那我要怎么修改呢？？

放到输入year以后把，year就不随机了！！谢谢版主的指点
