How to put up the receipt for my code?

[WanHazyan]

The question is here
Assume that your company is running a virtual architecture design business and your company is specialize in designing specific types of room. You need a system to keep record on your order all the orders made by customers systematically.

a) Record the customers’ orders using linked list implementation.
b) Your program should allow you to record each customer’s order of different virtual rooms and print the order details in a single receipt
Each receipt could record up to maximum 3 virtual rooms orders regardless the room type.
d) Your system should be able to provide all the functions listed below continuously based on user selection.
e) Apply stack concept, search and sort algorithms in your system design:
 Use Stack concept to handle UNDO request in order to remove the latest created record.  Provide search mechanism (Binary Search) to support the modification of specific customer order details.  Allow sorting mechanism (choose one - Bubble Sort or Selection Sort or Insertion Sort) based on customer order sequence (receipt number), customer’s name and room types.
f) Write a special method in main file to pre-define at least FIVE (5) receipts with various virtual room orders.

so,here is what I got to do so far

Header File

  #include <iostream>
#include <string>

#include <conio.h>
using namespace std;
string roomType;
int roomNumber;
int bed;
int table;
int towel;
int sofa;



class Node
{
public: 
	
	string roomType;
	int roomNumber;
	int bed;
	int table;
	int towel;
	int sofa;
	Node *next;

	Node(int x, string a, int b, int c, int d, int e, Node *z)
	{
		roomType = a;
		roomNumber = x;
		bed = b;
		table = c;
		towel = d;
		sofa = e;
		next = z;
	}
};



class Room
{
private:
	Node *head;
	int count;
public:
	Room();//Room(DoubleRoom);
	void Menu();
	void roomtype0(int); 
	void addRoom();
	void deleteRoom(int x);
	void viewRoom();
	
};

class Roomtype: Room
{
private:
	Node * head;
public:
	Roomtype();
	string single();
	string doubl();
	string supreme();

};
