Q:

C++ - Calling a class constructor from another class constructor

So I'm folowing a c++ course and on one excerise I need to use the constructor of a class named "Weapon" inside the constructor of a class named "Character" but each time when I try to compile the code it gives me this error :   
Character.cpp|13|error: no match for call to `(Weapon) (int&,std::__cxx11::string&)’|

even though I declared this exact constructor inside Weapon.h:
#ifndef WEAPON_H
#define WEAPON_H

#include <string>

class Weapon
{
public:
    Weapon();
    Weapon(int damage, std::string name);
    virtual ~Weapon();

    int GetDamage() { return m_damage; }
    void SetDamage(int val) { m_damage = val; }
    std::string GetName() { return m_name; }
    void SetName(std::string val) { m_name = val; }

private:
    int m_damage;
    std::string m_name;
};

#endif // WEAPON_H

Btw I'm French and it's my first time posting but I tried my best to translate the source code in english sorry if there's any mistakes or unintended meanings behind certain lines. Here are my Character.cpp / Weapon.cpp / Character.h files.
#include "Character.h"
#include "Weapon.h"

Character::Character()
{
    m_health_points = 100;
    m_mana = 100;
}

Character::Character(int damage, std::string name)
{
    m_health_points = 100;
    m_mana = 100;
    m_weapon(damage, name);
}

Character::~Character()
{
}

#include "Weapon.h"

Weapon::Weapon()
{
}

Weapon::Weapon(int damage, std::string name)
{
    m_damage = damage;
    m_name = name;
}

Weapon::~Weapon()
{
}

#ifndef CHARACTER_H
#define CHARACTER_H

#include "Weapon.h"

class Character
{
public:
    Character();
    Character(int damage, std::string name);
    virtual ~Character();

    int GetHealthPoints() { return m_health_points; }
    void SetHealthPoints(int val) { m_health_points = val; }
    int GetMana() { return m_mana; }
    void SetMana(int val) { m_mana = val; }

private:
    int m_health_points;
    int m_mana;
    Weapon m_weapon;
};

#endif // CHARACTER_H

A:

C++ has special construct for member variable initialization in constructors:
Character::Character(int damage, std::string name)
  : m_weapon(damage,name),
    m_health_points(100),
    m_mana(100)  
{
}
