Answer 1

#include <iostream>
#include <ctime>

class Student
{
	int id;
	int mark;
	public:
	    void getID(int _id) {
    		id = _id;
		}
		void getMark(int _mark) {
			mark = _mark;
		}
		void display() {
			std::cout << "id: " << id;
			std::cout << " Mark: " << mark << "\n";
		}
};

int main()
{
	Student st[5];
	
	srand((unsigned) time(0));

	for (int i = 0; i < 5; i++ ) {
	    int r = (rand() % 10) + 1;
		st[i].getID((i + r) * 10000 + r);
		st[i].getMark((i + r) * 10);
	}

	for (int i = 0; i < 5; i++) {
		st[i].display();
	}
	
	return 0;
}




/*
run:

id: 100010 Mark: 100
id: 70006 Mark: 70
id: 50003 Mark: 50
id: 120009 Mark: 120
id: 140010 Mark: 140
