在c ++中复制一个未知的具体类型

class Base {
public:
    virtual ~Base() {}
    virtual Base* clone() const = 0;
};

class Derived1 : public Base {
public:
    Derived1(const Derived1& other) {
        // 复制Derived1的成员变量
    }
    virtual Derived1* clone() const {
        return new Derived1(*this);
    }
};

class Derived2 : public Base {
public:
    Derived2(const Derived2& other) {
        // 复制Derived2的成员变量
    }
    virtual Derived2* clone() const {
        return new Derived2(*this);
    }
};

Base* copyUnknownType(Base* object) {
    return object->clone();
}
