@Coffee_Moew 最后要判断一下 sdm == 10

@Coffee_Moew

还有 sbm 要初始化

#include<bits/stdc++.h>
using namespace std;
int main()
{
    string isbn;
    int sbm = 0,sl=1;
    cin>>isbn;
    for(int i=0;i<isbn.size()-1;i++)
    if(isbn[i]!='-')
    {
        sbm=sbm+(isbn[i]-'0')*sl;
        sl++;
    }
    sbm=sbm%11;
    if(isbn[isbn.size()-1]-'0'==sbm||(isbn[isbn.size()-1]=='X'&&sbm==10)) cout<<"Right";
    else
    {
        for(int i=0;i<isbn.size()-1;i++) cout<<isbn[i];
        cout<<(sbm == 10 ? (char)'X' : char(sbm + '0'));
    }
    return 0;
}
