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

    int calculateTotalScore(){
    int sum = 0;

    This is my code if inputs were lines of string: class Student{ public: vector scores; void input(); int calculateTotalScore(); };

    void Student::input(){ string container; cin.ignore(); //delete the first "enter"

    //Parse
size_t start = 0;
while(true){
    string temp_container;
    size_t pos = container.find(' ', start);
    //When there's no "space"
    if (pos == string::npos){
        temp_container = container.substr(start);
        scores.push_back(stoi(temp_container));
        break;
    }
    //String parsing
    temp_container = container.substr(start, pos-start);
    start = pos + 1;
    scores.push_back(stoi(temp_container));
}

    } int Student::calculateTotalScore(){ int total =0; for (int i=0; i

    Here is my code!

    #include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
#include <cassert>
using namespace std;

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

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;
}
