直接拿万能头，string 类型就好了，没必要那么麻烦。

AC 代码

#include<bits/stdc++.h>
using namespace std;
int main(){
    string str,truely;
    int flag=0,num=1;
    cin>>str;
    truely=str;
    for (int i=0;i<12;++i){
        if(str[i]=='-')continue;
        flag=flag+(str[i]-'0')*num;
        num++;
    }
    if(flag%11==10)
    truely[12]='X';
    else
    truely[12]=flag%11+'0';
        if(str!=truely){
            cout<<truely<<endl;
        }else printf("Right");
    return 0;

}
