慢慢来.....到老的时候那也只能是慢慢来了！！！

呵呵
你最后一句的作用是什么啊

#include "stdio.h"
void main()
{
int year;
printf("please enter a year:");
scanf("%d",&year);
if((year%4==0&&year%100!=0)||year%400==0)
printf("%d is a leap year!\n",year);
else printf("%d is not a leap year!\n",year);

}
/*帮你修改了下， 有两个地方错误，自己看*/

#include "stdio.h"
void main()
{
int year;
printf("please enter a year:");
scanf("%d",&year);
if((year%4==0&&year%100!=0)||year%400==0)
printf("%d is a leap year!\n",year);
else printf("%d is not a leap year!\n",year);

}
