Acknowledgment
“Gratitude is the fairest blossom which springs from the soul”
Feeling gratitude and not expressing it is like wrapping a present and not giving it. We take
this opportunity to convey our heartfelt gratitude to each and every one who has supported us
in every way or the other during the course of our project.
From the very core of our heart, we would like to express our sincere gratitude to Miss. Dipti
for his supervisory guidance. We are always indebted to him for his kind support and
constant encouragement and his enthusiasm to complete our project milestones.
It requires lots of efforts in terms of cooperation and support to fulfill various tasks involved
during the project. We are always grateful to our peers and friends who have always
encouraged us and guided us whenever we needed assistance.
We also take this opportunity to express our appreciation to all the participants involved
during our preliminary research for their invaluable time to answer our queries and
suggestions for the application to be developed.
Things always remain hidden in the shadow of the unsung heroes; still we would to thank all
the people passively involved in the assignment, people who encouraged us day in and day
out to make it a success.
At last but above all, we thank the Almighty for his blessings.

INTRODUCTION
A typical luxury Hotel requires a management system to control its various
operations such as maintaining account of all the people in its domain of
services, attending to various needs of customers and also achieving increased
efficiency in the overall working of the Hotel itself.
1.1PURPOSE OF THE SYSTEM
The Hotel Management System aims to make simpler a staff’s interaction
with the various modules of the Hotel and ease the process of acquiring
information and providing services. The system can be accessed by the
admin and customers but the highest priority given to admin that are
allocated a login id and password. It will also allow cutting the operational
costs of the hotel.
1.2 SCOPE
In this system we will make extensive use of files system in C++.
We will have a login id system initially. In this system we will be having
separate functions for
Getting the information
Getting customer information who are lodged in
Allocating a room to the customer
Checking the availability
Displaying the features of the rooms.
Preparing a billing function for the customer according to his
room no.
In the software developed separate functions will be there for each of the
above points so that there is ample scope for adding more features in the
near future.
1.3 HARDWARE AND SOFTWARE REQUIREMENTS
The platform used is C++. Hence we decided to use Microsoft Visual
Studio 2010/2008 edition (Professional Edition).
For optional coding and easy debugging we used Microsoft Visual Studio 2008
edition and made explicit .cpp files.
Henceforth for optimal usage of such software a windows based operating
system preferably Windows vista/7/XP must be there. Also on the hardware part
any system having Windows Vista/7/XP installed will suffice.
2.0 Design Description
2.1 Interface Design
Fig: welcome screen
 Welcome Page where user get the info about the application.
Fig : Login Screen
 Login screen for admin and for customer here admin have the highest priority where
admin can add, delete, search, update and many more.
 Customer can view on availability of rooms
Fig : Admin Login
 Admin :- User name : admin
Password: admin
 Login page for admin. it is for security purpose . no one can access admin page . only
admin have the permission to handle records.
Fig : Admin Login
 Admin :- User name : admin
Password: admin

3.0 Description & Justification of OO concepts
3.1 Object
We used to create object to call the function which is related to any particular class we had
objects to call the function in this assignment. here we had created view object of class
customer to call the function welcomecreen() and loginscreen() functions to call then in main
functions
#include"customer.h"
using namespace std;
void main()
{
customer view;
view.welcomescreen();
view.login_screen();
}
3.2 Polymorphism
Complier is able to select the appropriate function for a particular call at the complie time
itself (also called as early binding )
we use polymorphism to access the variables from different class in this project we had use
polymorphism to get access the variables of customer class.
Code:
class Generatebill:public customer
3.3 Class
Bind the data and its associated functions together it allows data to be hidden if necessary
from external use defining a class we are creating a new abstract data type that can be treated
like other built – in data type
Code :
#ifndef H_M
#define H_M
#include<string>
#include<iomanip>
#include<iostream>
#include<fstream>
#include<conio.h>
#include<math.h>
#include<time.h>
using namespace std;
class customer
{
public:
int custm_id;
int custm_age;
int check_inyear;
int check_inmonth;
int check_indate;
char roomtype[20];
char custm_name[30];
int room_charge;
int compare(char[]);
char custm_occupation[20];
void getdata();
void putdata();
long total; //variable for Generate Bill
int food;
long room;
float ser;
int t;
int oc;
int r_day;
public:
void welcomescreen();
void login_screen();
void add_customer();
void delete_customer();
void update_customer();
void search_customer();
void main_screen();
void display_customer();
void checkout_customer();
void room_detail();
void generate_bill();
void room_bill();
};
#endif
3.3 Encapsulation
It is a process of wrapping up to data value and member in a single unit (class).
4.0 Description of Validation
In every project validation is the important parts while the development. In
Hotel Management System we had also provided proper validation to make
system error free. In this system we had provided validation in date month and
year to get proper date from administrator. The codes which we had used to get
proper validation in date system are mentioned below.
code:
cout<<"nEnter customer CheckIn Date : ";
START:
cout<<"n--------------------------------";
cout<<"nYear : ";
cin>>check_inyear;
cout<<"nMonth : ";
cin>>check_inmonth;
cout<<"nDate : ";
cin>>check_indate;
cout<<"nEnter Room Type : ";
cin>>roomtype;
cout<<"nEnter Room Charge : ";
cin>>room_charge;
if((check_inmonth==2) && (check_indate>29))
{
cout<<"wrong input!!!n";
cout<<"nenter the date again....n";
goto START;
}
if((check_inmonth>12)||(check_indate>31))
{
cout<<"wrong input!!!n";
cout<<"nenter the date again....n";
goto START;
}
if((check_inmonth==4||check_inmonth==6||check_inmonth==9||check_inmonth
==11) && (check_indate>30))
{
cout<<"wrong input!!!n";
cout<<"nenter the date again....n";
goto START;
}
if((check_inyear%4)!=0 && (check_inmonth==2) && (check_indate>28))
{
cout<<"wrong input!!!n";
cout<<"nenter the date again....n";
goto START;
}
We had use the validation in the adminstration login while entering the wrong
user name & password it show the popup menu.
cout<<"ttttUser Name = ";
cin>>username;
if(strcmp(username,"admin")==0)
{
string pass ="";
char ch;
cout <<"nttttPassword = ";
ch = _getch();
while(ch != 13)
{
pass.push_back(ch);
cout << '*';
ch = _getch();
}
if(pass == "admin")
{
cout <<"ntt"<< "Access granted";
do
{
}
}

7. CONCLUSION
At the end of this coursework, I was able to:
- Explain object oriented programming concepts and apply them to the modelling of
real world systems.
- Explain the object oriented paradigm and utilisation of the offered facilities.
- Demonstrate the ability to develop and derive new class structures and organise

  • 4. Acknowledgment “Gratitude is the fairest blossom which springs from the soul” Feeling gratitude and not expressing it is like wrapping a present and not giving it. We take this opportunity to convey our heartfelt gratitude to each and every one who has supported us in every way or the other during the course of our project. From the very core of our heart, we would like to express our sincere gratitude to Miss. Dipti for his supervisory guidance. We are always indebted to him for his kind support and constant encouragement and his enthusiasm to complete our project milestones. It requires lots of efforts in terms of cooperation and support to fulfill various tasks involved during the project. We are always grateful to our peers and friends who have always encouraged us and guided us whenever we needed assistance. We also take this opportunity to express our appreciation to all the participants involved during our preliminary research for their invaluable time to answer our queries and suggestions for the application to be developed. Things always remain hidden in the shadow of the unsung heroes; still we would to thank all the people passively involved in the assignment, people who encouraged us day in and day out to make it a success. At last but above all, we thank the Almighty for his blessings. Prince Kumar PT1082219

  • 6. INTRODUCTION A typical luxury Hotel requires a management system to control its various operations such as maintaining account of all the people in its domain of services, attending to various needs of customers and also achieving increased efficiency in the overall working of the Hotel itself. 1.1PURPOSE OF THE SYSTEM The Hotel Management System aims to make simpler a staff’s interaction with the various modules of the Hotel and ease the process of acquiring information and providing services. The system can be accessed by the admin and customers but the highest priority given to admin that are allocated a login id and password. It will also allow cutting the operational costs of the hotel. 1.2 SCOPE In this system we will make extensive use of files system in C++. We will have a login id system initially. In this system we will be having separate functions for Getting the information Getting customer information who are lodged in Allocating a room to the customer Checking the availability Displaying the features of the rooms. Preparing a billing function for the customer according to his room no. In the software developed separate functions will be there for each of the above points so that there is ample scope for adding more features in the near future.
  • 7. 1.3 HARDWARE AND SOFTWARE REQUIREMENTS The platform used is C++. Hence we decided to use Microsoft Visual Studio 2010/2008 edition (Professional Edition). For optional coding and easy debugging we used Microsoft Visual Studio 2008 edition and made explicit .cpp files. Henceforth for optimal usage of such software a windows based operating system preferably Windows vista/7/XP must be there. Also on the hardware part any system having Windows Vista/7/XP installed will suffice. 2.0 Design Description 2.1 Interface Design Fig: welcome screen  Welcome Page where user get the info about the application.
  • 8. Fig : Login Screen  Login screen for admin and for customer here admin have the highest priority where admin can add, delete, search, update and many more.  Customer can view on availability of rooms Fig : Admin Login  Admin :- User name : admin Password: admin  Login page for admin. it is for security purpose . no one can access admin page . only admin have the permission to handle records.
  • 9. Fig : Admin Login  Admin :- User name : admin Password: admin Fig : Admin screen  Options to handle records.
  • 10. Fig : Add_customer  Adding customer details Name ID ID_Proof Customer_occupation Customer_checkin Customer_checkout Fig : Add_customer1
  • 11. Fig : Display_Customer  Displaying the details of the customer
  • 12. Fig : Customer_bill Fig : Final_Bill  Calculating the overall bill by taking Cust_name , no. of stayed , room charges , other charges
  • 13. Fig : Update_customer  Updating the details of the customer by taking user name. Fig : search_customer  Customer can be searched by just taking the name of the customer
  • 16. 2.4 DFD 2.4.1 Context Diagram HOTEL MANAGEMENT SYSTEM ROOM CUSTOMER CUSTOMER CHECK_OUT
  • 18. 2.4.3. DFD-CHECK_OUT 3.0 Description & Justification of OO concepts 3.1 Object We used to create object to call the function which is related to any particular class we had objects to call the function in this assignment. here we had created view object of class customer to call the function welcomecreen() and loginscreen() functions to call then in main functions #include"customer.h" using namespace std; void main() { customer view; view.welcomescreen(); view.login_screen(); }
  • 19. 3.2 Polymorphism Complier is able to select the appropriate function for a particular call at the complie time itself (also called as early binding ) we use polymorphism to access the variables from different class in this project we had use polymorphism to get access the variables of customer class. Code: class Generatebill:public customer 3.3 Class Bind the data and its associated functions together it allows data to be hidden if necessary from external use defining a class we are creating a new abstract data type that can be treated like other built – in data type Code : #ifndef H_M #define H_M #include<string> #include<iomanip> #include<iostream> #include<fstream> #include<conio.h> #include<math.h> #include<time.h> using namespace std; class customer { public: int custm_id; int custm_age; int check_inyear; int check_inmonth; int check_indate; char roomtype[20]; char custm_name[30]; int room_charge; int compare(char[]);
  • 20. char custm_occupation[20]; void getdata(); void putdata(); long total; //variable for Generate Bill int food; long room; float ser; int t; int oc; int r_day; public: void welcomescreen(); void login_screen(); void add_customer(); void delete_customer(); void update_customer(); void search_customer(); void main_screen(); void display_customer(); void checkout_customer(); void room_detail(); void generate_bill(); void room_bill(); }; #endif 3.3 Encapsulation It is a process of wrapping up to data value and member in a single unit (class).
  • 21. 4.0 Description of Validation In every project validation is the important parts while the development. In Hotel Management System we had also provided proper validation to make system error free. In this system we had provided validation in date month and year to get proper date from administrator. The codes which we had used to get proper validation in date system are mentioned below. code: cout<<"nEnter customer CheckIn Date : "; START: cout<<"n--------------------------------"; cout<<"nYear : "; cin>>check_inyear; cout<<"nMonth : "; cin>>check_inmonth; cout<<"nDate : "; cin>>check_indate; cout<<"nEnter Room Type : "; cin>>roomtype;
  • 22. cout<<"nEnter Room Charge : "; cin>>room_charge; if((check_inmonth==2) && (check_indate>29)) { cout<<"wrong input!!!n"; cout<<"nenter the date again....n"; goto START; } if((check_inmonth>12)||(check_indate>31)) { cout<<"wrong input!!!n"; cout<<"nenter the date again....n"; goto START; } if((check_inmonth==4||check_inmonth==6||check_inmonth==9||check_inmonth ==11) && (check_indate>30)) { cout<<"wrong input!!!n"; cout<<"nenter the date again....n"; goto START; } if((check_inyear%4)!=0 && (check_inmonth==2) && (check_indate>28)) { cout<<"wrong input!!!n"; cout<<"nenter the date again....n"; goto START; } We had use the validation in the adminstration login while entering the wrong user name & password it show the popup menu. cout<<"ttttUser Name = "; cin>>username; if(strcmp(username,"admin")==0) { string pass =""; char ch; cout <<"nttttPassword = "; ch = _getch(); while(ch != 13) {
  • 23. pass.push_back(ch); cout << '*'; ch = _getch(); } if(pass == "admin") { cout <<"ntt"<< "Access granted"; do { } } 5.0 Implementation WELCOME SCREEN: void customer::welcomescreen() { system("cls"); cout<< endl << endl << endl<< endl; cout<<" COMPUTERISED MANAGEMENT SYSTEM "<<endl; cout<<" APIIT SD INDIA, PANIPAT "<< endl; cout<<" INDIVIDUAL ASSINGMENT "<< endl; cout<<" ON "<< endl; cout<<" Further Programming Concepts in C++ "<< endl; cout<<" (CE00314-2) "<<endl; cout<<" ____________________________________________________ "<< endl; cout<< endl << endl << endl<< endl; cout<<" SUBMITTED BY: SUBMITTED TO: "<<endl; cout<<" Prince kumar Ms. Deepti Dhingra "<<endl; cout<<" (PT082219) (LECTURER) "<<endl; cout<< endl << endl; cout<<" Press Enter to continue...." << endl << endl << endl << endl; getch(); }
