在派生类中使用虚函数

Question

In the following class, i'm aware the output will be:

Func A game

Func B game

Func A game

Func B game

and to fix it would be to make the Game functionB() virtual but I was just wondering why rpg->functionB() would call the method in the Game class as opposed to the RPG class? Can anyone help?

class Game  {

     public: Game() {}; 

    void functionA() {cout << "Func A game" << endl;}; 
    void functionB() {cout << "Func B game" << endl;}; 

};

class RolePlayGame: public Game { 

    public: RolePlayGame() {}; 
    void functionB(){ cout << "Func B role play" << endl; }; 

};

int main(){

    Game* g = new Game; Game* rpg = new RolePlayGame;

    g->functionA();
    g->functionB();
    rpg->functionA();
    rpg->functionB();
    delete g;
    delete rpg;

    return 0;
}

I don't see any functions declared virtual in your code. Only virtual functions are resolved at runtime; non-virtual functions are resolved at compile time, according to the static type.
