为什么全错啊

#include<bits/stdc++.h>
using namespace std;
int main(){
    string n;
    cin>>n;
    char a[n.size()]={0};
    for (int i = 0; i < n.size(); i++)
    {
        a[n.size()-i]=n[i];
    }
    for (int i = 0; i < n.size()+1; i++)
    {
        cout<<a[i];
    }
    return 0;
}

第二个循环的i初始化成1就可以了

#include<bits/stdc++.h>
using namespace std;
int main(){
    string n;
    cin>>n;
    char a[n.size()]={0};
    for (int i = 0; i < n.size(); i++)
    {
        a[n.size()-i]=n[i];
    }
    for (int i = 1; i < n.size()+1; i++)
    {
        cout<<a[i];
    }
    return 0;
}
