求大佬看看帮忙debug

include<iostream>

include<string>

include<cctype>

using namespace std;

int main() { char ch; string a; cin >> a; int c[10], i = 0, sum = 0; for (auto b : a) { if (isdigit(b)) { c[i] = b; i++; } } for (int x = 0; x < 9; x++) { sum = sum + c[x] * (x + 1); } sum %= 11; if (sum == c[10]) { cout << "right"; } else if (sum == 10) { ch = 'X'; a.pop_back(); a.push_back(ch); } else { a.pop_back(); ch = sum + '0'; a.push_back(ch); cout << a; }

return 0;

}```cpp

AC 我的代码


#include <bits/stdc++.h>
using namespace std;
int main()
{
    string i;
    cin >> i;
    int x;
    x = i[0] - '0'+ (i[2] - '0') * 2 + (i[3] - '0') * 3 + (i[4] - '0') * 4 + (i[6] - '0') * 5 + (i[7] - '0') * 6 + (i[8] - '0') * 7 + (i[9] - '0') * 8 + (i[10] - '0') * 9;
    x = x % 11;
    if (i[12] - '0' == x || (i[12] == 'X' && x == 10))
        cout << "Right" << endl;
    else
    {
        for (int l = 0; l <= 11; l++)
            cout << i[l];
        if (x == 10)
            cout << "X" << endl;
        else
            cout << x << endl;
    }
    return 0;
}

@marmotgreatagain 求您先把Latex修一修、

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

int main()
{
    string s;
    cin >> s;
    int sum = 0;
    int cnt = 0;
    for (int i=0; i<s.size()-1; i++) {
        if (s[i]!='-') {
            sum += (s[i]-'0') * ++cnt;
        }
    }
    int m = sum % 11;
    char c;
    if (m<10) c = m + '0';
    else c = 'X';
    if (s[s.size()-1] == c) cout << "Right";
    else {
        s[s.size()-1] = c;
        cout << s;
    }
    return 0;
}

另一种思路，希望能给你启发 @marmotgreattagain
