如何知道C++中所有者对象的地址？

#include<iostream>

class Owner {
public:
    int age;
};

int main() {
    Owner owner;
    owner.age = 30;

    // 创建一个指向Owner对象的指针
    Owner* ownerPtr = &owner;

    // 使用指针访问所有者对象的地址和成员
    std::cout << "Owner address: "<< ownerPtr<< std::endl;
    std::cout << "Owner age: "<< ownerPtr->age<< std::endl;

    return 0;
}
