@yuxinrui0618 这样吧，我把我代码发给你，你看看。下面是代码：

#include<iostream>
using namespace std;
int y[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};
int main(){
    int f,t;
    cin>>f>>t;
    int year=f/10000;
    int m=f%10000/100;
    int day=f%100;
    int sum=0;
    while(year*10000+m*100+day<=t){
        if(year%400==0||year%100!=0&&year%4==0){
            y[2]=29;
        }
        else{
            y[2]=28;
        }
        int a,b,c,d;
        d=m/10;
        c=m%10;
        b=day/10;
        a=day%10;
        if(d+10*c+100*b+1000*a==year){
            sum++;
        }
        if(day+1>y[m]){
            day=0;
            m++;
        }
        if(m>12){
            m=1;
            year++;
        }
        day++;
    }
    cout<<sum;
    return 0;
}
