例14：计算某日是该年的第几天

#include<stdio.h>#include<stdlib.h>int Test(int year,int month,int day){     static int d[2][12] = {0,31,59,90,120,151,181,212,243,273,304,334,                            0,31,60,91,121,152,182,213,244,274,305,335                           };          if(year%4 == 0)year = 1;     else year = 0;     return d[year][month-1]+day;}int main(){    int year,month,day;    while(~scanf("%d %d %d",&year,&month,&day))    {                     printf("%d\n",Test(year,month,day));    }    return 0;}

因为前面有很多我觉得很简单的所以这个就直接从这个开始了。如果这个博客上面没有的例子一定是我没写。
