class Compare//自定义排序

    bool operator()(const Person& p1, const Person& p2) const

        {
            if (p1.m_time == p2.m_time)
            {
                return p1.m_name < p2.m_name;
            }
            else return p1.m_time < p2.m_time;

int StringToInt(string s)
{
    int t;
    stringstream ss(s);
    ss >> t;
    return t;
}

void ShowRand(multiset& ms)
{
    for (multiset::iterator it = ms.begin(); it != ms.end(); it++)
    {
        cout << setw(10) << left << it->m_name << " " << setw(2) << right << it->m_qesnum
            << " " << setw(4) << right << it->m_time << endl;
    }
}

int main()
{
    int n, m;//题数 单位罚时
    cin >> n >> m;
    multiset ms;

    string name;
    while (cin>>name)//???如何停止循环
    {
        Person p;
        p.m_name = name;
        string record;//因为可能有括号用string不用int
        int count = 0, time = 0;

        for (int i = 0; i < n; i++)//记录每题的做题情况
        {
            cin >> record;
            if (record[0] != '0' && record[0] != '-')
            {
                count++;//统计AC题数
                int pos1 = record.find("(");//字符查找 未查找到返回-1
                if (pos1 == -1)//无错误提交
                {
                    time += StringToInt(record);
                }
                else//有错误提交 罚时
                {
                    time += StringToInt(record.substr(0, pos1));
                    int pos2 = record.find(")");
                    string wrong = record.substr(pos1 + 1, pos2 - pos1 - 1);
                    time += StringToInt(wrong) * 20;
                }
            }
        }

        p.m_qesnum = count;
        p.m_time = time;

        ms.insert(p);

    }
    ShowRand(ms);

    return 0;
}

Ctrl + z 键，输入结束直接回车即可结束while(cin>>name)循环。
