Answer 1

#include <iostream>
using namespace std;
class Student{
    int roll, marks;
    string name;
    public:
        Student(int r, int m, string s):roll(r), marks(m), name(s){}
        void display(){
            cout<<"Name: "<<name<<endl;
            cout<<"Roll: "<<roll<<endl;
            cout<<"Marks: "<<marks<<endl;
        }
};
int main(){
    Student *students[3];
    int r, m, max = INT_MIN, pos = 0;
    string s;
    for(int i = 0; i < 3; i++){
        cout<<"Enter name of student "<<i + 1<<": ";
        cin>>s;
        cout<<"Enter roll of student "<<i + 1<<": ";
        cin>>r;
        cout<<"Enter marks of student "<<i + 1<<": ";
        cin>>m;
        students[i] = new Student(r, m, s);
        if(m > max){
            max = m;
            pos = i;
        }
        cout<<endl;
    }
    cout<<"Student with the highest score is\n";
    students[pos]->display();
    return 0;
