?? 编译没过？？

by ssdmr @ 2021-09-26 21:07:33

应该有a[]吧？

by ssdmr @ 2021-09-26 21:08:13

错误都是显示在a[ ]上

by ssdmr @ 2021-09-26 21:09:26

@Lucashuang 应该是a的问题

by int64 @ 2021-09-26 21:09:59

@Lucashuang 应该定义 char 数组而不是单个 char 变量。

by int64 @ 2021-09-26 21:10:25

还有，

if(a[-1] == s){

是个什么鬼？

by ssdmr @ 2021-09-26 21:11:10

@Lucashuang 编译失败

        /tmp/compiler_s9kll_zv/src: 在函数‘int main()’中:

@Lucashuang 正解

#include<bits/stdc++.h>
using namespace std;
int main()
{
    char a[15];
    int i,sum=0,k=0,m=1;
    cin>>a;
    for(i=1;i<=11;i++)
    {
        if(a[k]-48<10&&a[k]-48>-1)
        {
            sum+=(a[k]-48 )*m;
            m++;
        }
        k++;
    }

    if(a[12]=='X'){
        if(sum%11==10){
            cout<<"Right";
        }
        else{
            for(i=0;i<=11;i++)
            {
                cout<<a[i];
            }
            if(sum%11==10)
            cout<<'X';
            else
            cout<<sum%11; 
        } 
    }
    else
    {
        if(sum%11==a[12]-48)
        {
            cout<<"Right";
        }
        else
        {
            for(i=0;i<=11;i++)
            {
                cout<<a[i];
            }

            cout<<'X';
