这边建议C++11正则表达式，简单省事，混乱邪恶

1、这边建议直接输入输出c

2、你输出13个字符干什么

3、c数组应该开15

#include<iostream>
using namespace std;
int main(){
    char c[15];
    int sum=0;int cnt=1;
    cin>>c;
    for(int i=0;i<11;i++){
        if(c[i]>='0'&&c[i]<='9'){
            sum=sum+(c[i]-'0')*cnt;
            cnt++;
        }
    }
    sum=sum%11;
    char s;
    if(sum==10)s='X';
    else s=sum+'0';
    if(s==c[12])cout<<"Right";
    else {
        c[12]=s;
        cout<<c;
    }return 0;
}
