用c加加写一个基类：过境人员，派生类：游客、卡车司机、商务旅客的长代码，具体要求1.从一个抽象基类和几个非抽象派生类创建一个层次结构。 2.在类描述中包含一个在创建对象后不会改变的唯一数字标识符： 3. 实现所有构造函数、必要的设置和获取方法、析构函数。 4.根据条件重新加载赋值运算符，比较运算符==，输出运算符到流<<。5.创建一个指向基类的指针数组，填充并对该数组进行一定的操作，以及统计每个类的对象个数。

以下是基类和派生类的长代码：

#include <iostream>
using namespace std;

class TransitPerson {
protected:
    int id;
    static int count;
public:
    TransitPerson(int id) : id(id) { count++; }
    virtual ~TransitPerson() { count--; }
    int getId() const { return id; }
    virtual void print() const = 0;
    static int getCount() { return count; }
};

int TransitPerson::count = 0;

class Tourist : public TransitPerson {
private:
    string name;
public:
    Tourist(int id, string name) : TransitPerson(id), name(name) {}
    ~Tourist() {}
    string getName() const { return name; }
    void setName(string name) { this->name = name; }
    void print() const { cout << "Tourist " << name << " with ID " << id << endl; }
};

class TruckDriver : public TransitPerson {
private:
    string licensePlate;
public:
    TruckDriver(int id, string licensePlate) : TransitPerson(id), licensePlate(licensePlate) {}
    ~TruckDriver() {}
    string getLicensePlate() const { return licensePlate; }
    void setLicensePlate(string licensePlate) { this->licensePlate = licensePlate; }
    void print() const { cout << "Truck driver with license plate " << licensePlate << " and ID " << id << endl; }
};

class BusinessTraveler : public TransitPerson {
private:
    string company;
public:
    BusinessTraveler(int id, string company) : TransitPerson(id), company(company) {}
    ~BusinessTraveler() {}
    string getCompany() const { return company; }
    void setCompany(string company) { this->company = company; }
    void print() const { cout << "Business traveler from " << company << " with ID " << id << endl; }
};

int main() {
    TransitPerson* people[3];
    people[0] = new Tourist(1, "Alice");
    people[1] = new TruckDriver(2, "ABC123");
    people[2] = new BusinessTraveler(3, "XYZ Inc.");

    for (int i = 0; i < 3; i++) {
        people[i]->print();
    }

    cout << "Total number of transit people: " << TransitPerson::getCount() << endl;

    for (int i = 0; i < 3; i++) {
        delete people[i];
    }

    return 0;
}

这个程序定义了一个抽象基类 TransitPerson 和三个派生类 Tourist、TruckDriver 和 BusinessTraveler。每个人都有一个唯一的数字标识符 id，并且可以打印自己的信息。程序还创建了一个指向基类的指针数组，填充并对该数组进行一定的操作，以及统计每个类的对象个数。
