蓝桥杯 基础练习（闰年判断）

坑点
注意 ==

# include<stdio.h>

int leap(int n)
{
    int ret;
    if(n%4 == 0 && n %100 != 0||n % 400 == 0){
        ret = 1;
    }
    else{
        ret = 0;
    }

    return ret;
}


int main()
{
    int year;
    int result = 0;

    scanf("%d", &year);
    result = leap(year);
    if (result == 1){
        printf("yes");
    }
    else{
        printf("no");
    }

    return 0;
}
