How to get the name of an Object - c++

Question

I am coding a little RPG(Role Playing Game)
Here is the situation: I created an object Personnage.
In my classes, I created a method atttaquer. But I would like that after calling my method attaquer it writes something like this: Goliath attaque David . But to that, I need to grab the name of the Object. Because the player may want to edit the name of Object (The personage name) before playing.
There is my code:
Personnage.h
#ifndef Personnage_h
#define Personnage_h
#include <string>
#include "Arme.h"
class Personnage{
//methods
public:
Personnage();
Personnage(std::string nomArme, int degatsArme);
Personnage(int vie, int mana);
// ~Personnage();
void recevoirDegats(int nbDegats);
void attaquer(Personnage &cible);
private:
// Attributs
int m_vie;
int m_magie;
std::string m_nom;
};
#endif
My Personnage.cpp code:
#include "Personnage.h"
#include <string>
#include <iostream>
void Personnage::recevoirDegats(int nbDegats){
m_vie -= nbDegats;
if (m_vie < 0) {
m_vie = 0;
}
}
void Personnage::attaquer(Personnage &cible){
cible.recevoirDegats(m_arme.getDegats());
// if David attacks Goliath I want to write std::cout << David << "attaque "<< Goliath << endl; but I do not know how to grab the name of the object after it's creation
}
There is my main.cpp
#include <iostream>
#include <string>
#include "Personnage.h"
//#include "Personnage.cpp"
#include <ctime>
using namespace std;
int main()
{
Personnage David, Goliath, Atangana("Ak47", 35);
Goliath.attaquer(David);
return 0;
}

If you want to give your objects names, it cannot be the variable names. They are only meant for the compiler and they are fixed. So you need to create a class that can have a name:
class NamedObject
{
private:
std::string m_name;
public:
const std::string& getName() const
{
return m_name;
}
void setName(const std::string& name)
{
m_name = name;
}
}
And if you want your classes to have a name, the easiest way would be to derive from it:
class Personnage : NamedObject {
Then you can say:
Personnage player1, player2;
player1.setName("David");
player2.setName("Goliath");
Alternatively, you can get those string from user input.
And if you need to address one by name:
std::cout << player1.getName() << " please make your move." << std::endl;
