判断是否为闰年？【C语言】

感觉就for有些别扭。对了也可以用其他方法l

#includ<stdio.h>
int main(){
    int year=0;
    printf("请输入年份：%d\n",year);
    scanf("%d\n",&year);
    for(;(year%4==0&&year%100!=0)||year%400==0;){
    printf("%d:是闰年\n",year);
}
    printf("不是闰年");
    return 0;
}

#include<stdio.h>

int main() {
    int year = 0;
    printf("请输入年份:");
    scanf("%d", &year);

    if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) {
        printf("%d:是闰年\n", year);
    } else {
        printf("%d:不是闰年\n", year);
    }

    return 0;
}

#include<stdio.h>
int main() {
	for (int year = 2000; year <= 2500; year++) {
		if (year % 4 == 0 && year % 100 != 0 || year % 400 == 0) {
			printf("%d:是闰年\n",year);

		}
		else
		{
			printf("%d:不是闰年\n",year);
		}
	}
}
