    class Student{ public : int score[5] , sum=0; void input(){ for(int i=0;i<5;i++){ cin>>score[i]; } } int calculateTotalScore(){ for(int i=0;i<5;i++){ sum+=score[i]; } return sum; } };

    My C++ code 

    class Student {

public:
    void input() {
        for(int & score : scores) {
            cin >> score;;
        }
    }

    int calculateTotalScore() {
        int total = 0;
        for(int i = 0;i < 5;i++) {
            total += scores[i];
        }
        return total;
    }
private:
    int scores[5] = {0};
};
