程序代码:
//自己写着玩的,是关于友元函数 #include<iostream> class Lovers { friend class Others; public: void kiss_action(); protected: void kiss(); private: }; class Girlfriend :public Lovers { public: void kiss_action(); protected: void kiss(); private: }; class Boyfriend :public Lovers { public: void kiss_action(); protected: void kiss(); private: }; class Others { //friend class Girlfriend; //friend class Lovers; public: void kiss_other(); protected: private: }; void Lovers::kiss() { std::cout<<"I want kiss"; } void Lovers::kiss_action() { Lovers::kiss(); } void Girlfriend::kiss() { Lovers::kiss_action(); std::cout<<"my girlfriend I am a normal boy"; } void Girlfriend::kiss_action() { Girlfriend::kiss(); } void Boyfriend::kiss() { Lovers::kiss_action(); std::cout<<"my boyfriend I am a gayboy"; } void Boyfriend::kiss_action() { Boyfriend::kiss(); } void Others::kiss_other() { Girlfriend::kiss_action();//“Girlfriend::kiss_action”: 非静态成员函数的非法调用 std::cout<<"I am a third..hehe"; } int main() { Lovers::kiss_action();//“Lovers::kiss_action”: 非静态成员函数的非法调用 Girlfriend::kiss_action();//“Girlfriend::kiss_action”: 非静态成员函数的非法调用 Boyfriend::kiss_action();//“Boyfriend::kiss_action”: 非静态成员函数的非法调用 Others::kiss_other(); return 0; }
