class Player { private: int killedMonsterCredit; public: Player() { killedMonsterCredit = 0; } void addKill() { killedMonsterCredit++; } int getKilledMonsterCredit() { return killedMonsterCredit; } }; // Usage: Player player; player.addKill(); // This adds one to the killed monster credit int credits = player.getKilledMonsterCredit(); // This gets the current number of killed monstersIn this example, we have a class called Player that has a private variable called killedMonsterCredit, initialized to zero in the constructor. The class also has two public methods: addKill() that adds one to the killedMonsterCredit, and getKilledMonsterCredit() that returns the current value of killedMonsterCredit. This code example might belong to a game development package library.
