有没有我们需要*C++中的受保护继承的例子？

#include<iostream>

class Base {
public:
    int public_member;

protected:
    int protected_member;

private:
    int private_member;
};

class Derived : protected Base {
public:
    void show() {
        std::cout << "Public member: "<< public_member<< std::endl;
        std::cout << "Protected member: "<< protected_member<< std::endl;
        // std::cout << "Private member: "<< private_member<< std::endl; // This line will cause a compilation error
    }
};

int main() {
    Derived d;
    d.public_member = 1;
    d.protected_member = 2;
    // d.private_member = 3; // This line will cause a compilation error
    d.show();
    return 0;
}
