Create array of objects for three students, compare their marks but make sure allocating memory to all the objects during run time only and display the records of the student who is getting highest score. 

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;
}
