Answer 1

#include <iostream>
#include <string>


using namespace std;


class Student {
private:
	string name;
	int rollNo;
	int mark;
public:
	Student(){}
	Student(string name,int rollNo,int mark){
		this->name=name;
		this->rollNo=rollNo;
		this->mark=mark;
	}
	void display() {
		cout<<"\nStudent name: "<<name<<"\n";
		cout<<"Student roll no: "<<rollNo<<"\n";
		cout<<"Student mark: "<<mark<<"\n\n";
	}
	//compare marks using operator overloading
	bool operator>(const Student &s1)
	{
		return (this->mark>s1.mark);
	}
};


int main(){
	//array of objects for three students
	Student students[3];
	students[0]=Student("Peter",12332,90);
	students[1]=Student("Mary",546454,75);
	students[2]=Student("Mike",874565,93);
	Student studentHighestScore=students[0];
	cout<<"All students: \n";
	for(int i=0;i<3;i++){
		students[i].display();
		if(students[i]>studentHighestScore){
			studentHighestScore=students[i];
		}
	}
	cout<<"\nThe student who is getting the highest score.\n";
	studentHighestScore.display();
	
	return 0;
