题目:输入某年某月某日,判断这一天是这一年的第几天?
#include<stdio.h>#include<stdlib.h>
void main()
{
int year,month,day,sum,leap;
printf("请输入您要的日期(__年__月__日)\n");
scanf("%d %d %d",&year,&month,&day);
printf("您输入的日期是%d年%d月%d日\n",year,month,day);
switch(month)
{
case 1:sum=0;break;
case 2:sum=31;break;
case 3:sum=59;break;
case 4:sum=90;break;
case 5:sum=120;break;
case 6:sum=151;break;
case 7:sum=181;break;
case 8:sum=212;break;
case 9:sum=243;break;
case 10:sum=273;break;
case 11:sum=304;break;
case 12:sum=334;break;
default:printf("输入日期错误,请检查!\n");break;
}
sum=sum+day;
if(year%400==0||(year%4==0&&year%100!=0))
leap=1;
else
leap=0;
if(leap==1&&month>2);
sum++;
printf("此日期是全年的第%d天\n",sum);
}
为什么日期天数老是不对,总是多一天,而且闰年3月以后根本不会自动多加一天啊,哪里错了?
还有调试的时候老是有个警告:warning C4390: ';' : empty controlled statement found; is this the intent?
