Answer 4

这个不用大神，就是一个简单的练习题。
#include<stdio.h>

int main()
{
int year;
printf("输入年份：\n");
scanf("%d",&year);
if(year%400==0)
printf("%d是润年！\n",year);
else if(year%100!=0&&year%4==0)
printf("%d是润年！\n",year);
else
printf("%d不是闰年！",year);
}

Answer 5

if((year%4==0&&year%100!=0)||year%400==0)printf("是闰年")；

Answer 6

#include<stdio.h>
void main()
{
int year,a;
printf("请输入年份：");
scanf("%d",&year);
if((year%4==0&&year%100!=0)||(year%400==0))
a=1;
else
a=0;
if(a==1)
printf("\n%d此年是闰年\n",year);
else printf("%d此年非闰年\n",year);

}

Answer 7

if((y%4==0&&y%100!=0)||(y%100=0&&y%400==0))
return true;
