Passing around an objects members

Question

I am working on a final project for class and am having a little trouble. When I create my hero or monster object and assign it values, which is what i was checking with the commented out section in main, I am unable to access that info. For instance in my function to fight where I call the monster.Attack() the name of the warrior or mage object comes up blank. If I run a quick cout everything looks good except for the Hero objects members like name, type, maxHealth, maxMana, but the weapon name etc shows up. Any help would be greatly appreciated!

void CreateCharacters(Hero &mage, Hero &warrior, Monster &monster){

    monster.CreateWeapon("Mighty Club", 15);
}

int ShowMenu(){

    int choice;

    cout << "\nWelcome to the Battle!" << endl;
    cout << "----------------------" << endl;
    cout << "Please make a choice from the following:" << endl;
    cout << "1. Fight Now!" << endl;
    cout << "2. Quit" << endl;

    cin >> choice;

    return choice;
}

void Fight(Hero &mage, Hero &warrior, Monster &monster){

    std::cout << "\nYou have chosen to fight!" << endl;
    Sleep(3000);
    monster.Attack(mage, warrior, monster);

}

int main(){

    Hero mage;
    Hero warrior;
    Monster monster;

    CreateCharacters(mage, warrior, monster);

    do {
        int choice = ShowMenu();

        if (choice == 1){

            Fight(mage, warrior, monster);

        } else if (choice == 2){

            break;

        }
    } while (true); 

    cin.ignore();
    cin.get();

    return 0;
}

Whats also confusing to me is that the monster.Attack() function properly displays the health decremented for the mage or warrior but wont display on a cout.

Here is the output of the little cout test I did, notice the top 4 and about halfway through the other four referencing the objects herotype, name, maxHealth and maxMana dont register.

I think the problem is the argument names are the same as your member variable names:

void CreateHero(std::string name, int maxHealth, int maxMana, Hero::e_HeroType heroType){
        name = name; // Assigning member variable to itself.
        ...

Try changing to:

void CreateHero(std::string a_name, int a_maxHealth, int a_maxMana, Hero::e_HeroType a_heroType){
        name = a_name;
        ...
