Classes and Objects : How to pass value to method void input()?

Question

The requirement is Main() is fixed I can only change Student class.
Thank you for help.

class Student {
private:
int scores;
public:
Student() {
scores = 0;
}
void input() {
scores += scores;
}
int calculateTotalScore() {
int totScore;
totScore = scores;
return totScore;
}
};

in the main area:

int main() {
int n; // number of students
cin >> n;
Student *s = new Student[n]; // an array of n students

for(int i = 0; i < n; i++){
s[i].input();
}

// calculate kristen's score
int kristen_score = s[0].calculateTotalScore();

// determine how many students scored higher than kristen
int count = 0;
for(int i = 1; i < n; i++){
int total = s[i].calculateTotalScore();
if(total > kristen_score){
count++;
}
}

// print result
cout << count;

return 0;
}

Answer 1

this is the correct answer you need to loop.

class Student
{
private:
int scores[5];
int sum;

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

Answer 2

define your method like this:

void input()
{
int score;
cin >> score;
scores+=score;
}

Answer 3

but i can't edit the main() area: s[i].input();
