定义年份再输入,一层模四看整除,一百在,看四百,最后输出就结束。

#include<iostream> using namespace std; bool isLeap(int n){return n%4 == 0&&n%100!=0||n%400==0;} int n; int main(){ cin >> n; cout << (isLeap(n)?"Y":"N") << endl; return 0; }

就是判断(四年一闰,一百年不闰,四百年再闰),所以判断代码是: if (a % 4 == 0 && a %100 != 0 || a % 400 == 0)

解题方法如下: #include<iostream> using namespace std; int main(){ int n; cin>>n; if(n%40){ if(n%1000){ if(n%400==0){ cout<<"Y"; }else{ cout<<"N"; } }else{ cout<<"Y"; } }else{ cout<<"N"; } return 0; }
