@lancdn 您if里面写错了应该是：

if(i%400==0||(i%4==0&&i%100!=0))

@lancdn i%100!=0

完整代码

#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

if(i%4==0||(i%400==0&&i%100==0))

改为

if((i%4==0&&i%100!=0)||(i%400==0&&i%100==0))
