@[lancdn](/user/301765) 您if里面写错了应该是：
```
if(i%400==0||(i%4==0&&i%100!=0))
```

完整代码
```cpp
#include<iostream>
using namespace std;
int main(){
int kaishi,jieshu,i,m=0; //m:计数器
cin>>kaishi>>jieshu;
for(i=kaishi;i<=jieshu;i++){
if((i%4==0&&i%100!=0)||(i%400==0&&i%100==0)){
m++;
}
}
cout<<m<<endl;
for(i=kaishi;i<=jieshu;i++){
if((i%4==0&&i%100!=0)||(i%400==0&&i%100==0)){
cout<<i<<" ";
}
}
return 0;
}
```
注意闰年判断的时候%4==0时要判断是否%100！=0
举个栗子
1900不是闰年 但是1900%4==0
所以要把
```cpp
if(i%4==0||(i%400==0&&i%100==0))
```
改为
```cpp
if((i%4==0&&i%100!=0)||(i%400==0&&i%100==0))
```
