用c语言判断是否为闰年,C语言判断闰年

#include

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);

1.你要清楚什么样的年份才是闰年(能被4整除且不能被100整除或者能被400整除的。

2. 判断语句

if(  ((0 == year%4)&&(0 != year%100)) ||(0 == year %400) )

{//满足该条件的yeat就是闰年。}

以下是源程序代码：

#include

int main (void) {

int year;

printf ("please a year:");

scanf ("%i",&year);

if((year%4==0 && year%100!=0)||year%400==0){  printf ("%i is a leap year!",year);}else{  printf ("%i is not a leap year!",year);}

return 0;}
