改了一下

#include<bits/stdc++.h>
using namespace std;
int sum,cnt,n;
string s,e; 
void print()
{
    for(int i=0;i<n-1;i++)
    {
        cout<<s[i];
    }
    return ;
}
int main()
{
    cin>>e;
    n=s.size();
    s=e;
    for(int i=0;i<n-1;i++)
    {
        if(s[i]=='-')
            continue;
        s[i]-='0';
        cnt++;
        sum+=cnt*s[i];
    }
    if(sum%11==10)
    {
        if(s[n-1]=='X')
        {
            cout<<"Right";
            return 0; 
        }
        print();
        cout<<"X";
        return 0;
    }
    if(s[n-1]!=sum%11)
    {
        print();
        cout<<sum%11;
        return 0;
    }
    else
    {
        cout<<"Right";
        return 0;
    }
    return 0;
}

@2012zxt string的原型是这样的：

namespace std {
  typedef basic_string<char> string;
}

也就是说，string里存的东西是char。
