如何将相同的对象添加到多态数组中，但又能够对该对象的复制版本进行更改？

#include <iostream>
#include <vector>

class Object {
public:
    virtual Object* clone() const = 0;
    virtual void print() const = 0;
};

class ConcreteObject : public Object {
public:
    ConcreteObject* clone() const override {
        return new ConcreteObject(*this);
    }

    void print() const override {
        std::cout << "Concrete Object" << std::endl;
    }
};

int main() {
    std::vector<Object*> objects;

    ConcreteObject obj;
    objects.push_back(&obj);

    ConcreteObject* objCopy = obj.clone();
    objects.push_back(objCopy);

    // 修改复制版本
    objCopy->print();

    // 修改原始对象
    obj.print();

    return 0;
}
