bool ReadFileToArray(char fileName[], char strLine[100][3], int &nArrLen) { //fileName[]存放文件名 strLine[][3]存放结点的二维数组 nArrLen返回二叉树结点个数 FILE *pFile; char str[1000]; //存放读取一行文本的字符串 pFile = fopen(fileName, "r"); if (!pFile) { printf ("二叉树文件读取失败\n"); return false; } //读取文件第一行，判断二叉树标识BinaryTree是否正确 if (fgets (str, 1000, pFile) != NULL) { if (strcmp (str, "BinaryTree\n") == 0) { printf ("打开文件格式错误\n"); fclose (pFile); return false; } } nArrLen = 0; //循环读取结点行数据存入数组，结点总数加1 while (fscanf (pFile, "%c %c %c\n", &strLine[nArrLen][0], &strLine[nArrLen][1], &strLine[nArrLen][2]) != EOF) nArrLen++; fclose (pFile); return true; }

这段代码定义了一个ReadFileToArray函数，函数的作用是从文件中读取二叉树的结点数据，并将其存储到一个二维字符数组中。函数的参数包括文件名fileName、存放结点数据的二维字符数组strLine和结点个数nArrLen。

函数首先打开文件并检查是否成功打开，如果文件打开失败则返回false。然后读取文件的第一行，判断二叉树标识是否正确，如果不正确则返回false。接着进入一个循环，每次读取一行结点数据并存储到二维字符数组中，同时结点个数增加1。最后关闭文件并返回true。

需要注意的是，该函数中的文件操作使用了C标准库函数fopen、fgets和fscanf，需要在代码文件中包含头文件stdio.h。另外，该函数中使用了一个引用类型的参数nArrLen，表示函数执行结束后该参数的值会被修改。

class RoomManager { private: // Conference Room 1, the smaller one. // Only require the date information for appointment. set<int> _room1; // Conference Room 2, the bigger one. // Require both date and event information for appointment. map<int, string> _room2; public: // Insert an appointment to the smaller Conference Room (1). bool InsertAppointment(const int& date); // Insert an appointment to the bigger Conference Room (2). bool InsertAppointment(const int& date, const string& event); // Cancel an appointment on designated date. // If room_id == 1, cancel the corresponding appointment of _room1. // If room_id == 2, cancel the corresponding appointment of _room2. bool CancelAppointment(const int& room_id, const int& date); // Print all existing appointments in chronological order. // If room_id == 1, just print the date information.

，我们可以使用 RoomManager 类来管理两个会议室的预约信息。其中，Conference Room 1 只需要日期信息即可进行预约，而 Conference Room 2 需要日期和事件信息才能进行预约。

下面是完整的 RoomManager 类的代码实现：

#include <iostream>
#include <set>
#include <map>

using namespace std;

class RoomManager {
private:
    // Conference Room 1, the smaller one.
    // Only require the date information for appointment.
    set<int> _room1;

    // Conference Room 2, the bigger one.
    // Require both date and event information for appointment.
    map<int, string> _room2;

public:
    // Insert an appointment to the smaller Conference Room (1).
    bool InsertAppointment(const int& date) {
        if (_room1.find(date) != _room1.end()) {
            // There is already an appointment on this date.
            return false;
        } else {
            _room1.insert(date);
            return true;
        }
    }

    // Insert an appointment to the bigger Conference Room (2).
    bool InsertAppointment(const int& date, const string& event) {
        if (_room2.find(date) != _room2.end()) {
            // There is already an appointment on this date.
            return false;
        } else {
            _room2[date] = event;
            return true;
        }
    }

    // Cancel an appointment on designated date.
    // If room_id == 1, cancel the corresponding appointment of _room1.
    // If room_id == 2, cancel the corresponding appointment of _room2.
    bool CancelAppointment(const int& room_id, const int& date) {
        if (room_id == 1) {
            if (_room1.find(date) != _room1.end()) {
                _room1.erase(date);
                return true;
            } else {
                // There is no appointment on this date.
                return false;
            }
        } else if (room_id == 2) {
            if (_room2.find(date) != _room2.end()) {
                _room2.erase(date);
                return true;
            } else {
                // There is no appointment on this date.
                return false;
            }
        } else {
            // Invalid room_id.
            return false;
        }
    }

    // Print all existing appointments in chronological order.
    // If room_id == 1, just print the date information. Each piece of information is separated by ' '.
    // If room_id == 2, print the information in form of "date(event)". Each piece of information is separated by ' '.
    // If there is no even one existing appointment yet, print "No Appointment".
    void PrintAppointments(const int& room_id) const {
        if (room_id == 1) {
            if (_room1.empty()) {
                cout << "No Appointment";
            } else {
                for (const auto& date : _room1) {
                    cout << date << " ";
                }
            }
        } else if (room_id == 2) {
            if (_room2.empty()) {
                cout << "No Appointment";
            } else {
                for (const auto& appointment : _room2) {
                    cout << appointment.first << "(" << appointment.second << ") ";
                }
            }
        } else {
            // Invalid room_id.
            cout << "Invalid room_id";
        }
        cout << endl;
    }
};

int main() {
    RoomManager rm;

    rm.InsertAppointment(20220101);
    rm.InsertAppointment(20220102, "Meeting with John");
    rm.InsertAppointment(20220103);
    rm.InsertAppointment(20220102, "Meeting with Peter");

    rm.PrintAppointments(1);
    rm.PrintAppointments(2);

    rm.CancelAppointment(1, 20220103);
    rm.CancelAppointment(2, 20220102);

    rm.PrintAppointments(1);
    rm.PrintAppointments(2);

    return 0;
}

这里的 main 函数演示了 RoomManager 类的使用方法。我们可以看到，通过 RoomManager 类，我们可以方便地进行会议室预约、取消预约和打印预约信息等操作。
