@Mark_666 输出时不用打s[i]-'0',改为s[i]就能过了

。？

@Mark_666 又是我，照着你的代码稍微改了一些，即可AC

#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;
}

@liyong5114 为啥输出不能-'0'啊，没搞懂

by rnf5114 @ 2023-05-13 09:52:15

@Mark_666下划线可能会被减

@Mark_666 因为要输出'-'的话，就不能用"-'0'"了
