(padding for leap years):

1. A leap year that can be divisible by 4 and not divisible by 100

2. The century can be divisible by 400 is a leap year

#include<iostream>intmain(){    intyear;    std::cout<<"请输入年份:";    std::cin>>year;             //输入待判断年份,如2008    std::cout<<year<<(((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) == 1 ? "年是闰年": "年是平年")<<std::endl;    return0;}
