This post presents a hotel management project implemented in C++. The software provides various functionalities such as room reservation, customer data management, client updates, and viewing assigned rooms. The project extensively utilizes two fundamental C++ principles: classes and file manipulation.
Features of Hotel Management System in C++
- Manage Rooms
- Check-In
- Get available rooms
- Search customer
- Check-out room
- Get guest summary report
Program Breakdown
#include <iostream>
#include <string.h>
#include <conio.h>
#define max 100
using namespace std;
We will include all essential library files to prevent errors and set the maximum value as 100 beforehand.
class Customer
{
public:
char name[100];
char address[100];
char phone[12];
char from_date[20];
char to_date[20];
float payment_advance;
int booking_id;
};
We have designed a customer class that includes attributes such as a name field with a length of 100 characters, an address field with a capacity of 100 characters, a phone number field accommodating up to 12 characters, a start date field with a size of 20 characters, an end date field also with a size of 20 characters, a paymentadvance field of float data type, and a bookingid field of integer type.
class Room
{
public:
char type;
char stype;
char ac;
int roomNumber;
int rent;
int status;
class Customer cust;
class Room addRoom(int);
void searchRoom(int);
void deleteRoom(int);
void displayRoom(Room);
};
We have defined a classroom class with integer variables such as category, subcategory, air conditioning, roomNumber, rental cost, and availability status. An instance of the customer class named cust has been instantiated.
class Room rooms[max];
int count = 0;
We have defined an array rooms[max] of the room class as a global variable, with a count initialized to 0.
Room Room::addRoom(int rno)
{
class Room room;
room.roomNumber = rno;
cout << "\nType AC/Non-AC (A/N) : ";
cin >> room.ac;
cout << "\nType Comfort (S/N) : ";
cin >> room.type;
cout << "\nType Size (B/S) : ";
cin >> room.stype;
cout << "\nDaily Rent : ";
cin >> room.rent;
room.status = 0;
cout << "\n Room Added Successfully!";
getch();
return room;
}
Within the addroom function, an instance of the room class is instantiated to handle the addition of rooms based on customer requirements. It prompts the user to specify if the room should have air conditioning (AC) or not, followed by selecting the comfort level and size of the room - either Standard (S) or Big (B). Additionally, the user is asked to input the daily rental rate, which can be adjusted as necessary. The rooms have been successfully added.
void Room::searchRoom(int rno)
{
int i, found = 0;
for (i = 0; i < count; i++)
{
if (rooms[i].roomNumber == rno)
{
found = 1;
break;
}
}
if (found == 1)
{
cout << "Room Details\n";
if (rooms[i].status == 1)
{
cout << "\nRoom is Reserved";
}
else
{
cout << "\nRoom is available";
}
displayRoom(rooms[i]);
getch();
}
else
{
cout << "\nRoom not found";
getch();
}
}
This search_room function is designed to locate an existing room if it is present. When a customer inputs a room number, the function will display the room details if the room is located.
void Room::displayRoom(Room tempRoom)
{
cout << "\nRoom Number: \t" << tempRoom.roomNumber;
cout << "\nType AC/Non-AC (A/N) " << tempRoom.ac;
cout << "\nType Comfort (S/N) " << tempRoom.type;
cout << "\nType Size (B/S) " << tempRoom.stype;
cout << "\nRent: " << tempRoom.rent;
}
This function will present the available rooms to the customer based on their selection of room number, AC preference, comfort level, and room size.
class HotelMgnt : protected Room
{
public:
void checkIn();
void getAvailRoom();
void searchCustomer(char *);
void checkOut(int);
void guestSummaryReport();
};
This class is designed for managing hotel operations, offering functionalities such as check-in, room availability check, customer search, check-out, and generating summary reports.
void HotelMgnt::guestSummaryReport()
{
if (count == 0)
{
cout << "\n No Guest in Hotel !!";
}
for (int i = 0; i < count; i++)
{
if (rooms[i].status == 1)
{
cout << "\n Customer First Name : " << rooms[i].cust.name;
cout << "\n Room Number : " << rooms[i].roomNumber;
cout << "\n Address (only city) : " << rooms[i].cust.address;
cout << "\n Phone : " << rooms[i].cust.phone;
cout << "\n---------------------------------------";
}
}
The function named getsummary retrieves the summary of an existing customer if one is found, and it also allows us to input a new summary. The process involves requesting the customer's first name, room number, address, and phone number.
// hotel management reservation of room
void HotelMgnt::checkIn()
{
int i, found = 0, rno;
class Room room;
cout << "\nEnter Room number : ";
cin >> rno;
for (i = 0; i < count; i++)
{
if (rooms[i].roomNumber == rno)
{
found = 1;
break;
}
}
if (found == 1)
{
if (rooms[i].status == 1)
{
cout << "\nRoom is already Booked";
getch();
return;
}
cout << "\nEnter booking id: ";
cin >> rooms[i].cust.booking_id;
cout << "\nEnter Customer Name (First Name): ";
cin >> rooms[i].cust.name;
cout << "\nEnter Address (only city): ";
cin >> rooms[i].cust.address;
cout << "\nEnter Phone: ";
cin >> rooms[i].cust.phone;
cout << "\nEnter From Date: ";
cin >> rooms[i].cust.from_date;
cout << "\nEnter to Date: ";
cin >> rooms[i].cust.to_date;
cout << "\nEnter Advance Payment: ";
cin >> rooms[i].cust.payment_advance;
rooms[i].status = 1;
cout << "\n Customer Checked-in Successfully..";
getch();
}
}
If a client intends to reserve a room, this script will be triggered. The client will input the room number. In case the room is already reserved, a message will be displayed indicating that the room is already booked. If the room is available, the system will prompt for the booking ID, customer's name, address, phone number, preferred date for the room reservation, and the advance payment amount. Subsequently, a message will be displayed confirming the successful check-in of the customer.
void HotelMgnt::getAvailRoom()
{
int i, found = 0;
for (i = 0; i < count; i++)
{
if (rooms[i].status == 0)
{
displayRoom(rooms[i]);
cout << "\n\nPress enter for next room";
found = 1;
getch();
}
}
if (found == 0)
{
cout << "\nAll rooms are reserved";
getch();
}
}
The function mentioned above will display the rooms that are currently available. In case a specific room is already reserved, the system will indicate with a flag that all rooms have been reserved.
// hotel management shows all persons that have booked room
void HotelMgnt::searchCustomer(char *pname)
{
int i, found = 0;
for (i = 0; i < count; i++)
{
if (rooms[i].status == 1 && stricmp(rooms[i].cust.name, pname) == 0)
{
cout << "\nCustomer Name: " << rooms[i].cust.name;
cout << "\nRoom Number: " << rooms[i].roomNumber;
cout << "\n\nPress enter for next record";
found = 1;
getch();
}
}
if (found == 0)
{
cout << "\nPerson not found.";
getch();
}
}
The provided code snippet will search for a customer based on the user's input of the customer's name. If the specified customer is not found in the system, a message indicating "person not found" will be displayed.
// hotel managemt generates the bill of the expenses
void HotelMgnt::checkOut(int roomNum)
{
int i, found = 0, days, rno;
float billAmount = 0;
for (i = 0; i < count; i++)
{
if (rooms[i].status == 1 && rooms[i].roomNumber == roomNum)
{
// rno = rooms[i].roomNumber;
found = 1;
// getch();
break;
}
}
if (found == 1)
{
cout << "\nEnter Number of Days:\t";
cin >> days;
billAmount = days * rooms[i].rent;
cout << "\n\t######## CheckOut Details ########\n";
cout << "\nCustomer Name : " << rooms[i].cust.name;
cout << "\nRoom Number : " << rooms[i].roomNumber;
cout << "\nAddress : " << rooms[i].cust.address;
cout << "\nPhone : " << rooms[i].cust.phone;
cout << "\nTotal Amount Due : " << billAmount << " /";
cout << "\nAdvance Paid: " << rooms[i].cust.payment_advance << " /";
cout << "\n*** Total Payable: " << billAmount - rooms[i].cust.payment_advance << "/ only";
rooms[i].status = 0;
}
getch();
}
The code snippet above is employed to produce the invoice for a client.
void manageRooms()
{
class Room room;
int opt, rno, i, flag = 0;
char ch;
do
{
system("cls");
cout << "\n### Manage Rooms ###";
cout << "\n1. Add Room";
cout << "\n2. Search Room";
cout << "\n3. Back to Main Menu";
cout << "\n\nEnter Option: ";
cin >> opt;
// switch statement
switch (opt)
{
case 1:
cout << "\nEnter Room Number: ";
cin >> rno;
i = 0;
for (i = 0; i < count; i++)
{
if (rooms[i].roomNumber == rno)
{
flag = 1;
}
}
if (flag == 1)
{
cout << "\nRoom Number is Present.\nPlease enter unique Number";
flag = 0;
getch();
}
else
{
rooms[count] = room.addRoom(rno);
count++ ;
}
break;
case 2 :
cout << " \ n Enter room number : " ;
cin >> rno ;
room.searchRoom ( rno ) ;
break ;
case 3 :
// nothing to do
Break ;
default :
cout << " \ n Please Enter correct option " ;
break ;
}
} while ( opt != 3 ) ;
}
The provided code snippet is utilized for handling various room-related functions such as adding new rooms, searching for rooms, or returning to the main menu.
