注意数组的预处理，不要用switch case

#include <stdio.h>int leapmonth[12] = {0,31,29,31,30,31,30,31,31,30,31,30}; //闰年0~11月int commonth[12] = {0,31,28,31,30,31,30,31,31,30,31,30};//平年0～11月int main(){    int year,month,day,i,count;    while(scanf("%d/%d/%d",&year,&month,&day)!=EOF)    {        count=0;        if((year%4==0&&year%100!=0)||(year%400==0))//闰年            for(i=0;i<month;i++)//累加0~month-1 月的天数                count+=leapmonth[i];        else//平年            for(i=0;i<month;i++)//累加0~month-1 月的天数                count+=commonth[i];        count+=day;//累加当前月份天数        printf("%d\n",count);    }    return 0;}
