#include<iostream>
using namespace std;

int main(){
    int a,i;
    cin>>a;
    int k[a];
    for(i=0;i<a;i++){
                     cin>>k[a];
                     int y=k[i];
                     if((y%4==0&&y%100>0)||(y%400==0))
                     cout<<"Case "<<i+1<<": a leap year"<<endl;
                     else
                     cout<<"Case "<<i+1<<": a normal year"<<endl;
                          }
                        
     system("pause");
     return 0;
     }

可是我輸入1900年

他卻出現a leap year 耶

怎麼會這樣??

總算AC了

謝謝你~大好人
