#include<iostream>
using namespace std;

class Person
{
	double ID;
	string name;
	string address;
  public:
  	Person():ID(0),name(""),address(""){}
 	Person(double _ID, string _name, string _address)
 	:ID(_ID), name(_name), address(_address){}
 	void SetPerson()
 	{
 		cout<<"\nPlease, enter an ID for new person:";
 		cin>>ID;
 		cout<<"Please, enter a name for new person:";
 		cin>>name;
 		cout<<"Please, enter an address of new person:";
 		cin.ignore(256,'\n');
 		getline(cin,address,'\n');
	}
	void PrintPerson()
	{
		cout<<"\nData of the person:"
			<<"\nID: "<<ID
			<<"\nName: "<<name
			<<"\nAddress: "<<address;
	}
};

class Student:public Person
{
	int rollnumber;
	string marks;
  public:
  	Student():Person(),rollnumber(0),marks(""){}
  	Student(double _ID, string _name, string _address, int _rollnumber, string _marks)
  	:Person(_ID, _name,_address),rollnumber(_rollnumber),marks(_marks){}
  	void SetStudent()
	{
		cout<<"\nPlease, enter a rollnumber for new student:";
 		cin>>rollnumber;
 		cout<<"Please, enter marks for new student:";
 		cin>>marks;
	}	
	void PrintStudent()
	{
		cout<<"\nData of the student:"
			<<"\nRollnumber: "<<rollnumber
			<<"\nMarks: "<<marks;
	}	
};

int main()
{
	Student a(123,"Alex","5 street",4,"A,B,C,D,E");
	a.PrintPerson();
	a.PrintStudent();
	Student b;
	b.SetPerson();
	b.SetStudent();
	b.PrintPerson();
	b.PrintStudent();
