Thread: Incrementing/Decrementing Object's hitpoints using classes

I can't seem to increment/decrement an object's hitpoints in a game. For example...

Code:

#include <iostream>

class Player
{
public:
     int getHitPoints() const { return HitPoints; }
     void setHitPoints(int hit) { HitPoints = hit; }
private:
     int HitPoints;
};

int main()
{
     using namespace std;
     
     Player Bob;
     Bob.setHitPoints(10);

     cout << "Bob gets hit!" << Bob.getHitPoints() - 2 << endl;

     return 0;
}

Any help is appreciated.
