@yjy_fywy 这地狱马蜂

#include<bits/stdc++.h>
using namespace std;
int main(){
    int a,b,c,d,e,f,g,h,i,qwe,j1;
    char q,j,k;
    cin>>a>>q>>b>>q>>e>>q>>j;
    if(j=='X'){
        j1=10;
    }else{
        j1=j-'0';
    }
    d=b%10,c=b/10%10,b/=100;
    i=e%10,h=e/10%10,g=e/100%10,f=e/1000%10,e/=10000;
    qwe=a+b*2+c*3+d*4+e*5+f*6+g*7+h*8+i*9;
    qwe%=11;
    if(qwe==10){
        k='X';
    }else if(qwe<10){
        k=qwe+'0';
    }
    if(k!=j){
        cout<<a<<"-"<<b<<c<<d<<"-"<<e<<f<<g<<h<<i<<"-"<<k;
    }else{
        cout<<"Right";
    }
    return 0;
}

@yjy_fywy char数组+循环结构会更好用

#include<bits/stdc++.h>
using namespace std;
int main() {
    char isbn[15];
    int ans=0,x=1;
    cin>>isbn;
    for(int i=0;i<12;i++){
        if(isbn[i]!='-'){
            if(isbn[i]!='X'){
                ans+=x*(isbn[i]-'0');
                x++;
            }else{
                ans+=x*10;
                x++;
            }
        }
    }
    ans%=11;
    if(ans==isbn[12]-'0'||(isbn[12]=='X'&&ans==10)) cout<<"Right";
    else{
        for(int i=0;i<=11;i++){
            cout<<isbn[i];
        }
        if(ans!=10) cout<<ans;
        else cout<<"X";
    }
    return 0;
}
