    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};
};

    **For Those Wants To Execute This Code Without Using Vector **

    #include <iostream>
using namespace std;

// Define the Student class
class Student {
private:
    int scores[5]; // Array to hold scores (fixed size for 5 subjects)

            totalScore += scores[i];
        }
        return totalScore;
    }
};

int main() {
    int n; // Number of students

    // Input scores for each student
    for (int i = 0; i < n; i++) {

    1. include

      using namespace std; class Student{ private: int q1,q2,q3,q4,q5; public: void input(){ cin >> q1 >> q2 >> q3 >> q4 >> q5; } int calculateTotalScore(){ int score; score += q1+q2+q3+q4+q5; return score; }}; int main() { int n; // number of students cin >> n; Student *s = new Student[n]; for(int i = 0; i < n; i++){ s[i].input(); } int kristen_score = s[0].calculateTotalScore(); int count = 0; for(int i = 1; i < n; i++){ int total = s[i].calculateTotalScore(); if(total > kristen_score){ count++; } } cout << count; return 0; }
