谢谢各位，AC了，以下为AC代码供参考

#include<bits/stdc++.h>
using namespace std;
int l,r;
int ans=0;
int a[2000];
int main(){
    cin>>l>>r;
    for(int i=l;i<=r;i++){
            if(i%400==0){
                ans++;
                a[ans]=i;
                continue;
            }
        if(i%4==0&&i%100!=0){
            ans++;
            a[ans]=i;
        }
    }
    cout<<ans<<endl;
    for(int i=1;i<=ans;i++){
        cout<<a[i]<<" ";
    }
    return 0;
}
