C语言闰年代码

#include <stdio.h>

void main()

{

int year,leap;

scanf("%d",&year);

if(year%4==0)

{

if(year%100!=0)

leap=1;

else

{

if(year%400==0)

leap=1;
1

else

leap=0;
1

}

}

if(leap==1)

printf("%d是闰年n",year);

else

printf("%d不是闰年n",year);}

公历闰年实现代码二：

#include <stdio.h>

void main()

{

int year,leap;

scanf("%d",&year);

if(year%4000||year%40&&year%100!=0)

printf("%d是闰年n",year);

else

printf("%d不是闰年n",year);

}

公历闰年实现代码三：

#include<stdio.h>

int main()

{

int year;

year=1900;

while(year<=2000)

{

if(year%4000||year%40&&year%100!=0)

{

printf("%d是闰年n",year);

year++;

}

else year++;

}

return 0;

}
