Answer 1

#include <iostream>
#include <string>
using namespace std;

class Student {
private:
    string name;
    int roll;
    int marks;

public:
    Student(string name, int roll, int marks);
    string getName() const {
        return name;
    }
    int getRoll() const {
        return roll;
    }
    int getMarks() const {
        return marks;
    }
    void display() const;
};

Student::Student(string name, int roll, int marks) :
    name(name), roll(roll), marks(marks)
{}

void Student::display() const
{
    cout << "Name: " << name << endl;
    cout << "Roll #: " << roll << endl;
    cout << "Makes " << marks << endl;
}

int main() {
    Student* A = new Student("Alice", 123, 98);
    Student* B = new Student("Bobe", 124, 87);
    Student* C = new Student("Charly", 125, 89);

    Student* best = A->getMarks() > B->getMarks() ? A : B;
    best = best->getMarks() > C->getMarks() ? best : C;
    cout << "The student with the highest score:" << endl;
    best->display();

    delete A;
    delete B;
    delete C;
}
