c语言 已知能被 4 整除但不能被 100 整除或者能被 400 整除的年份是闰年。请编程判断一个年份是否是闰年。
·
#include <stdio.h>
int main()
{
int year;
scanf("%d", &year);
if( year%4 == 0 )
{
if(year%100 == 0)
{
if( year%400 == 0 )
{
printf("%d is a leap year.", year);
}
else
{
printf("%d is not a leap year.", year);
}
}
else
{
printf("%d is a leap year.", year);
}
}
else
{
printf("%d is not a leap year.", year);
}
return 0;
}
