Comment ça marche

Ce sont des fonctions ayant le même nom mais prenant des paramètres différents

Fonctionne sur n'importe quelle fonction

#ifndef SAMPLE_CLASS_HPP
# define SAMPLE_CLASS_HPP

class Sample {

public:

    Sample(void);
    ~Sample(void);

    void    bar( char const c) const;
    void    bar( int const n) const;
    void    bar( float const z) const;
    void    bar( Sample const & i) const;
};

# endif

le fichier .cpp

#include <iostream>
#include "Sample.class.hpp"

Sample::Sample(void) {
    std::cout << "Constructor called" << std::endl;
    return;
}

Sample::~Sample(void) {
    std::cout << "Destructeur called" << std::endl;
    return;
}

void    Sample::bar( char const c) const{
    std::cout << "Member function called with char overload : " << c << std::endl;
    return;
}

void    Sample::bar( int const n) const {
    std::cout << "Member function called with int overload : " << n << std::endl;
    return;
}

void    Sample::bar( float const z) const {
    std::cout << "Member function called with float overload : " << z << std::endl;
    return;
}

void    Sample::bar( Sample const &i) const {
    (void)i;
    std::cout << "Member function called with Sample overload" << std::endl;
    return;
}

Constructor called
Member function called with char overload : a
Member function called with int overload : 42
Member function called with float overload : 3.14
Member function called with Sample overload
Destructeur called
