@[Eric20091204](/user/646545) 考虑一下您代码的判断优先级
by Escapism @ 2022-01-21 20:23:23
@[Eric20091204](/user/646545) 您的优先级：
```cpp
% 4 == 0 -> % 100 == 0 输出？
-> % 400 === 0 输出
```
正确的：
```cpp
% 4 == 0 -> % 100 == 0 不输出
-> % 100 != 0 输出
% 400 == 0 -> 输出
```cpp

@[Eric20091204](/user/646545) 因此，您的代码不能只简单地 / 4来求个数

@[Eric20091204](/user/646545) 顺便问问，您是小六的吗

```
#include<bits/stdc++.h>
using namespace std;
int main() {
int x, y, ans = 0;
vector<int> v;
cin >> x >> y;
for (int i = x; i <= y; i++) {
if ((i % 4 == 0 && i % 100) || i % 400 == 0) {
v.push_back(i);
ans++;
}
}
cout << ans << endl;
for (auto c: v) cout << c << " ";
return 0;
}

```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
int p,q;
cin>>p>>q;
int a=p,c=0;
for(;a<=q;){
if((a%4==0 && a%100!=0) || a%400==0){
c=c+1;
}
a=a+1;
}
cout<<c<<endl;
a=p ;
for(;a<=q;){
if((a%4==0 && a%100!=0) || a%400==0){
cout<<a<<" ";
c=c+1;
}
a=a+1;
}
cout<<endl;
return 0;
}
```
你用这个试试，应该可以AC。
