如何在C++中返回对基类的引用

#include <iostream>

class Base {
public:
    void print() {
        std::cout << "This is the base class." << std::endl;
    }
};

class Derived : public Base {
public:
    void print() {
        std::cout << "This is the derived class." << std::endl;
    }
};

Base& returnBaseReference() {
    static Derived derivedObj;  // 创建派生类对象
    return derivedObj;  // 返回对基类的引用
}

int main() {
    Base& baseRef = returnBaseReference();  // 获取对基类的引用
    baseRef.print();  // 调用基类的成员函数
    return 0;
}

This is the derived class.
