#include<iostream>
using namespace std;


class Base {
public:
	static int m_A;

};

int Base::m_A = 100;

class son :public Base {
public:
	static int m_A;
};
int son::m_A = 200;

int main() {
	son s;
	cout << "通过对象访问" << endl;
	cout << "son 下 m_A=" << s.m_A << endl;
	cout << "Base 下 m_A=" << s.Base::m_A << endl;
	cout << "通过类名访问" << endl;
	cout << "son 下 m_A=" << son::m_A << endl;
	cout << "Base 下 m_A=" << son::Base::m_A << endl;
	return 0;
}

同名成员函数

  • 如果子类中出现和父类同名的成员函数，子类的同名成员会隐藏掉父类中所有的同命成员函数
  • 如果访问到父类中被隐藏的同名成员函数，需要加作用域
