将派生类中的对象插入到所述对象的另一个实例中(使用vector.insert函数) C++

#include <iostream>
#include <vector>

class Base {
public:
    virtual void print() {
        std::cout << "Base" << std::endl;
    }
};

class Derived : public Base {
public:
    void print() override {
        std::cout << "Derived" << std::endl;
    }
};

int main() {
    std::vector<Base*> objects;
    Base* baseObj = new Base();
    Derived* derivedObj = new Derived();

    objects.push_back(baseObj);

    std::vector<Base*>::iterator it = objects.begin();
    objects.insert(it, derivedObj);

    for (Base* obj : objects) {
        obj->print();
    }

    // 释放内存
    delete baseObj;
    delete derivedObj;

    return 0;
}
