logical way to do object suicide with pointers, also an example of move semantics

suicide.cpp

#include <iostream>
#include <memory.h>
#include <utility>
#include <vector>

class human;
typedef std::unique_ptr<human> human_ptr;
typedef std::vector<human_ptr> humans_obj;

class human {
public:
    /* constructor */
    human(int _x, humans_obj* _h): x(_x) {
        h = _h;
        std::cout << "human " << x << " being born at " << this << std::endl;
    };
    /* destructor */
    ~human(){
        std::cout << "human " << x << " being killed at " << this << std::endl;
    };
    /* suicide */
    void suicide(){
        std::cout << "human " << x << " suiciding at " << this << std::endl;
        for(auto it = h->begin(); it != h->end(); it++){
            if(it->get() == this){
                std::cout << "i found myself!" << std::endl;
                h->erase(it);
            }
        };
    };
    
    /* print out human */
    friend std::ostream& operator<<(std::ostream& os, human& h) {
        return os << "human " << h.x << " says hi"  << std::endl;
    }
private:
    int x;
    humans_obj* h;
};

int main(){
    
    humans_obj house1;
    humans_obj house2;
    for(int i=1; i<4; i++){
        house1.push_back(std::make_unique<human>(i,&house1));
    }
    for(auto &h : house1){
        std::cout << *h;
    };
    std::cout << "size of house1 " << house1.size() << std::endl;
    house1[0]->suicide();
    std::cout << "size of house1 " << house1.size() << std::endl;
    
    std::cout << "who is in house1 " << std::endl;
    for(auto &h : house1){
        std::cout << *h;
    };
    
    std::cout << "moving house" << std::endl;
    house2.push_back(std::move(house1[0]));
    house1.erase(house1.begin());
    std::cout << "size of house1 " << house1.size() << std::endl;
    std::cout << "size of house2 " << house2.size() << std::endl;
    
    std::cout << "who is in house1 " << std::endl;
    for(auto &h : house1){
        std::cout << *h;
    };
    
    std::cout << "who is in house2 " << std::endl;
    for(auto &h : house2){
        std::cout << *h;
    };
    
    
    return 0;
}

may need a custom move constructor or something to update the humans_obj* h within the person when they move house?
