@EkSulfur yn函数写成这样：

    int a=0;
    if (x % 4 == 0&&x%100!=0||x%400==0)
        a =!a;
    return a;

#include <bits/stdc++.h>
using namespace std;

int main()
{
    int x, y;
    cin >> x >> y;
    int cnt = 0;
    for (int i = x; i <= y; i++)
    {
        if (i % 400 == 0 || i % 100 != 0 && i % 4 == 0)
        {
            cnt++;
        }
    }
    cout << cnt << endl;
    for (int i = x; i <= y; i++)
    {
        if (i % 400 == 0 || i % 100 != 0 && i % 4 == 0)
            cout << i << " ";
    }
    return 0;
}

@EkSulfur 可以看看我的

#include<bits/stdc++.h>

using namespace std;

bool r(long long i){

    if(i%4==0 && i%100!=0 || i%400==0 && i%3200!=0) return 1;

    else return 0;

}

int main()

{

    ios::sync_with_stdio(false);

    cin.tie(0), cout.tie(0);

    long long x,y,a=0;

    cin>>x>>y;

    for(int i=x;i<=y;++i){

        if(r(i)) a++;

    }

    cout<<a<<endl;

    for(int j=x;j<=y;++j){

        if(r(j)) cout<<j<<" ";

    }

    return 0;

}
