Passing a variable from main into a public class function?

I was wondering how in this situation I can pass a variable from main into a public class function. In this situation the health variable doesn't change at all even though it should. Here's my code:

class PlayerCharacter
{
public:
    void SetHealth(int Health)
{
    m_health = Health;
}
int GetHealth()
{
    return m_health;
}
private:
int m_health;
int m_maxhealth;
};


int main()
{
    PlayerCharacter PC;
    bool playing = true;
    int Choice;
    int v1;
    int v2;
    while (playing)
    {
        PrintMainMenu();
        cout << "Set Health And Max Health" << endl;
        cin >> Choice;
        v1 = Choice;
        cin >> Choice;
        v2 = Choice;
        PC.SetHealth(v1);
        PC.SetMaxHealth(v2);

        system("CLS");
    }
return 0;
}

Is there something I'm missing here? Thanks.
