for(int i=0, j=1;i<11;i++)

改成

for(int i=0, j=1;i<11;i++)

还有

cout << b << "    " << ISBN[12] << endl;

不要

@zrj2012 写错了

@zrj2012

for(int i=0, j=1;i<11;i++)

改成

for(int i=0, j=1;i<12;i++)

@kuxiaowo 算了，看我代码吧。

#include<bits/stdc++.h>
using namespace std;
string s;
int t=1;
long long sum;
int main(){
    cin>>s;
    for(int i=0;i<12;i++){
        if(s[i]-'0'>=0&&s[i]-'0'<=9){
            sum+=(s[i]-'0')*t;
            t++;
        }
    }
    sum=sum%11;
    if(sum==10){
        if(s[12]=='X')
            cout<<"Right";
        else{
            for(int i=0;i<12;i++)
                cout<<s[i];
            cout<<'X';
        }
    }
    else{
        if(s[12]-'0'==sum)
            cout<<"Right";
        else{
            for(int i=0;i<12;i++)
                cout<<s[i];
            cout<<sum;
        }
  }
    return 0;
}

就AC了

@kuxiaowo 懂我代码吧？
