当基类和派生类具有相同的变量名时，访问基类成员变量地址

#include <iostream>

class Base {
public:
    int variable;
};

class Derived : public Base {
public:
    int variable;
};

int main() {
    Derived derivedObj;
    derivedObj.variable = 10;
    derivedObj.Base::variable = 20;

    std::cout << "Derived variable: " << derivedObj.variable << std::endl;
    std::cout << "Base variable: " << derivedObj.Base::variable << std::endl;

    return 0;
}

Derived variable: 10
Base variable: 20
