要用单分支做，所以判断条件复杂了点。纯手打，希望你看得懂。
#include<stdio.h>
void main()
{
int year;
printf("Enter Year:");
scanf("%d",&year);
if((year%100==0&&year%400==0)||(year%100!=0&&year%4==0))
printf("It is leap year");
else
printf("It is common year");
getch();

void is_rn(int year)
{
printf("请输入年份：\n");
scannf("%d",&year);
if(year%4==0&&year%400!=0||yera%100==0)
{
printf("%d是闰年",year);
}
else
printf("%d是平年",year);
}
{
printf("请输入年份：\n");
scannf("%d",&year);
if(year%4==0&&year%400!=0||yera%100==0)
{
printf("%d是闰年",year);
}
else
printf("%d是平年",year);
}
