Introduction:
Object Oriented Programming in C++
The prime purpose of C++ programming was to add object orientation to the C programming language,
which is in itself one of the most powerful programming languages. The core of the pure object-oriented
programming is to create an object, in code, that has certain properties and methods. While designing
C++ modules, we try to see whole world in the form of objects. Object Oriented programming is a
programming style that is associated with the concept of Class, Objects and various other concepts
revolving around these two, like Inheritance, Polymorphism, Abstraction, Encapsulation etc.
Let us try to understand a little about all these, through a simple example. Human Beings are living
forms, broadly categorized into two types, Male and Female. Right? Its true. Every Human being(Male or
Female) has two legs, two hands, two eyes, one nose, one heart etc. There are body parts that are
common for Male and Female, but then there are some specific body parts, present in a Male which are
not present in a Female, and some body parts present in Female but not in Males. All Human Beings
walk, eat, see, talk, hear etc. Now again, both Male and Female, performs some common functions, but
there are some specifics to both, which is not valid for the other. For example : A Female can give birth,
while a Male cannot, so this is only for the Female. Human Anatomy is interesting, isn't it? But let's see
how all this is related to C++ and OOPS. Here we will try to explain all the OOPS concepts through this
example and later we will have the technical definitons for all this.
There are a few principle concepts that form the foundation of object oriented programming −
Object:-
This is the basic unit of object oriented programming. That is both data and function that operate on
data are bundled as a unit called as object.
Class:-
When you define a class, you define a blueprint for an object. This doesn't actually define any data, but
it does define what the class name means, that is, what an object of the class will consist of and what
operations can be performed on such an object.
Abstraction:-
Data abstraction refers to, providing only essential information to the outside world and hiding their
background details, i.e., to represent the needed information in program without presenting the details.
For example, a database system hides certain details of how data is stored and created and maintained.

2
Similar way, C++ classes provides different methods to the outside world without giving internal detail
about those methods and data.
Encapsulation:-
Encapsulation is placing the data and the functions that work on that data in the same place. While
working with procedural languages, it is not always clear which functions work on which variables but
object-oriented programming provides you framework to place the data and the relevant functions
together in the same object.
Inheritance
One of the most useful aspects of object-oriented programming is code reusability. As the name
suggests Inheritance is the process of forming a new class from an existing class that is from the existing
class called as base class, new class is formed called as derived class. This is a very important concept of
object-oriented programming since this feature helps to reduce the code size.
Polymorphism
The ability to use an operator or function in different ways in other words giving different meaning or
functions to the operators or functions is called polymorphism. Poly refers to many. That is a single
function or an operator functioning in many ways different upon the usage is called polymorphism.
Overloading
The concept of overloading is also a branch of polymorphism. When the exiting operator or function is
made to operate on new data type, it is said to be overloaded.

Project explanation:
Idea:-
project is a project for managing the hotel rooms and reservation throw multi features that help to
register,checkin,add rooms and other features .
Code explanation:
We will start by explaining every piece of code in the project and for that we will explain the functions
then we will gather all the pieces to make a running managing hotel rooms program
Notes: we will write Arabic explanation on code screens to make it clear
We will need to classes Customer and Rooms
Input:-
Customer class

4
Room Class
Then we will will need a Hotel management class for putting our functions in
Hotel management class
It has 5 main functions in it listed in the screen above

5
We now start with the first function which is Check in()
Check in secreen1

7
2. Get Avilable Rooms() to check if there is available room

8
3. searchcustomer() to search if this customer is reserving a room

9
4. Check out() to checkout from room

10
5.getsummeryreport() to get a report about the status of hotel

11
Now the Main() finction will contain all the options in hotel including add rooms
Main secreen1
