leap_year.c

通过此程序可以把输入的年份判别是平年,还是闰年.

#include<stdio.h>

void main()
{
	int year;
	int k=0;
	for(year=2000; year<=2500; year+=1)
	{
		if(year%100==0)
		{
			if(year%400==0)				
				printf("%d是闰年\n",year);
			else
			{
			    printf("%d不是闰年\n",year);
			    continue;
			}
		}
		else
		{
			if(year%4==0)
				printf("%d是闰年\n",year);
			else
				printf("%d不是闰年\n",year);
		}
	}
}
