@slry666 t是整形赋值‘X’？

@slry666

改成这样：

#include<bits/stdc++.h>
using namespace std;

long long j,len,i,sum;
string s,a;

signed main()
{
    cin>>s;
    len=s.length();
    j=1;
    for(i=0;i<len-1;i++)
    {
        if(s[i]=='-') continue;
        sum+=(s[i]-'0')*j; j++;
    }
    int t=sum%11;
    char ch;
    if(t==10) ch='X';
    else ch=t+'0';
    if(ch==s[len-1]) cout<<"Right";
    else{ s[len-1]=ch; cout<<s; }
    return 0;
}
