用c语言编辑程序：
//四年一闰,百年不闰,四百年再闰
#include <stdio.h>
int main()
{
int count = 0;
int year = 0;
for(year = 1000;year <=2000;year++)
{
if(year % 4 == 0)
{
if(year % 100 != 0)
{
printf("%d ",year);
count++;
}
}
if(year % 400 == 0)
{
printf("%d ",year);
count++;
}
}
printf("\n count = %d\n",count);
return 0;
}
输出结果：
