C++调用父类的重载运算符

有关运算符重载部分https://blog.csdn.net/qq_58665528/article/details/122420553 

#include 

class Person {
private:
	int m_age;

public:
	Person(int age) : m_age(age){}

	Person& operator=(const Person& person) {
		this->m_age = person.m_age;

		return *this;
	}

	void getAge() {
		std::cout << this->m_age << std::endl;
	}
};

class Student : public Person {
private:
	int m_id;

public:
	Student(int age = 0, int id = 0) : Person::Person(age), m_id(id){}	//初始化父类和子类的私有变量

	Student& operator=(const Student& student) {
		Person::operator=(student);	//调用父类的重载运算符，这样父类的私有变量也能赋值了
		this->m_id = student.m_id;

		return *this;
	}

	void getIdAge() {
		Person::getAge();
		std::cout << this->m_id << std::endl;

	}
};

int main(void) {
	Student s = Student(10, 2001);
	Student ss = s;

	ss.getIdAge();
	return 0;
}
