INTRODUCTION TO C++
“Language shapes the way we think and determines what we can think about”
C++ is one of the latest, dynamic and powerful environments for programming. C++ was
developed by Bjarne Stroustrup in the Bell laboratories in the early 1980’s. This section
reveals some of the features and advantages of c++.
Two languages contributed to its design-C, which provided low level features and simula
67,which provided the class concept.
C++ is an example of an object-oriented language. Other OOP language includes Smalltalk
and Ada.
EVOLUTION OF THE NAME C++
Rick Mascitti coined the name c++ in the summer of 1983. The name signifies the
evolutionary nature of the change from C. “++” is an increment operator. The slightly
shorter name C+ is the syntax error. Connoisseurs ofC semantics find C++ inferior to ++C.
The language is not called D, because it is an extension of C and does not attempt to remedy
problems by removing features.
SOME OF THE FEATURES OF C++
The reason for the popularity of C++ can by easily understood by its obvious features.
i) POWER AND FLEXIBILITY

C++ is an highly flexible, versatile and the very powerful programming language
for developing any software especially the system software namely operating
systems, compilers, editors, databases.
ii) MAINTAINABILITYAND REUSABILITY
C++ is most ideally suited for development of reusable software, that is, a
software which can be used for wide variety of problems with no little change.
This results in cost reduction of software development.
iii) PORTABILITY
C++ is machine independent, this means that a software development for a
particular computer system can be used on other computers with no or little
change.
iv) RELIABILITYREGULARITYAND READABILITY
C++ is reliable, regular and provides a lot of facilities for the simple codes to be
made reliable. Its efficiency is very high, making it every programmers favorite
environment.
WHY C++ IS CALLED A MIDDLE LEVEL LANGUAGE:
C++ is called a middle level language, not because its standard is lower than high level
languages, but due to the fact that it combines the best features of assemble language and
those of high level languages.
C and C++ posses the efficiency of low level languages and the user – friendliness of high
level languages so instead of calling it a middle level language, C++ can be more
appropriately called a hybrid programming language.
HOW C++ IN IMPROVEMENT OVER C?

C++ is officially known as superset of the C language. C++ retains all of C’s strength
interface its low level system programming, and its efficiency, economy and powerful
expressions.
In addition to these inherited features C++ introduces the dynamic world of object
programming and creates a platform for high level program abstraction. C++ accomplishes
all this with a simplicity and support for modularity while maintaining the compactness
and execution ifficiency of C. Due to these reasons the increment operator is addes to the
original name C thus making the new enhanced version, C++.
BASE OF C++
The C language has itself evolved partly under the influence of the development of C++.
The ANSI C standard contains function dexlaration syntax borrowed from “C with classes”.
Borrowing works both ways for example, the void * pointer type was invented for ANSI C
and first implemented in C++. C++ lays emphasis on modularity, strongly typed interfaces
and flexibility.
A SHORT NOTE ON OOP FACILITY OF C++
C++ has introduced object oriented programming to the world. C++ treats data and
operation that can be performed on the data as an object and an object is treated as a class.
So when a software is developed for a class rather than for individual data items, the
software developed for the class is applicable to all the objects in the class. This results in
the development of reusable software.
PURPOSE OF C++

ABOUT THE PROJECT
This project mainly concentrates on online booking of tickets for the
movies. This C++ program uses concepts like classes, data files
handiling and makeup the whole program’s using switch cases. It
allows the user to search for the movie by entering the movie name,
enable to view the list of all movies running in the theatre. This also
allows the user to book tickets for the movie he prefers. This
program will be easily accessible by the management staff of the
theatre to insert or delete movie from the theatre. This provides a
great help for both the staff and the user to maintain and preserve
their records.
Thus the project has been designed in such a fashion that even a
common man understands it and can operate it. Thus it’s simplicity
and wide utility has directed me to choose this project in this era of
entertainment.

DOCUMENTATION
This program is been compiled by using Borland turbo C++ v 8.0.
The working of the program is quite simple. It starts off by displaying a
men8 as given below.
1.Searching
2.Booking
3.Insertion
4.Deletion
5.About
6.Exit
 When the user chooses option 1:
The program directs the user to a screen where 3 options
are displayed showing the user , which are, search by movie
name , view list of all movies or to return ot main menu.
When the user chooses option:-
1.The program asks the user to enter the movie name to be
searched. The program will now search the file for the
details of the movie. If the movie name in the file matches

the name entered by the user then the corresponding
details will be displayed.
2.The program displays all the names of the movie present
in the file.
3.The program directs the user to the main menu.
When the entered option does not match in any file it
displays “Movie not found” and returns to the main menu.
The program directs the user to the screen where it asks the
user to enter the movie name for which he wants to book a
ticket. If the name of the movie entered matches with the
movies available.
When the entered option does not match any in file it
displays “Wrong option” and returns to the main menu.
 When the user chooses option 3 :
This option directs him to a screen where it asks him to
enter the password for insertion of records. Then it asks for
movie name, screen number , movie type and ticket cost
and movie capacity. After entering it asks whether do you
want to insert more records. When the password entered is
wrong it shows a message “Wrong password” and directs
him to the main menu.
The program directs the user to the screen where it asks him
to enter password for deletion of records. Then it asks for
the movie name to be deleted. Then it deletes the movie
and shows the option the movie has been deleted. Do you
want to delete more records. If the entered password is

wrong it shows a message “Wrong password” and directs
him to the main menu.
The program directs the user to a screen where 3 options
are displayed showing the user , which are about the
program, about the programmers, return to the main menu.
When the user enters option:-
1.It displays details about the program and how the program
is executed.
2.It displays details about the programmers.
3.The program directs him to the main menu.
The program exits and shows a message “ENJOY(‘-‘)”
followed by “BYEEE….”. This statement shows that the user
is going to exit from the program.

HEADER FILES USED AND THEIR PURPOSE
FSTREAM.H – for file handling, cin and cout
CONIO.H – for clrscr() and getch() functions
STDIO.H – for standard I/O operations
DOS.H – for execution of program
STRING.H – for string handling
TIME.H – for time and local time functions

LABLES USED:-
This program makes use of certain number of labels. They are :
 a:
 s:
 h:
 m:
With the help of ‘goto’ function, the program will be directed to the
respective label.
Class cinema:-
This class stores the essential details of the movies running in
the theatre. They variables stored in the program to store these details
are :-

Private members:-
 screenno
 mov_type
 cost
Public members:-
 mov_name
 cap
The class also has 2 public member functions namely:-
 get_data()
 put_data()
void main():-
This function reads the number from the user as to operate on
which operation is to be carried out. Then it is switched to the
respective operation such as searching, booking, insertion, deletion and
exiting.

Variables used for manipulating are as shown below:-
INTEGER VARIABLES:-
 dd
 mm
 yy
 choice[0]
 choice[1]
 i
 n
 k
 z
 j
 rnum
CHARACTER VARIABLES:-
 mov

 f
 nam
 ch
 cha
 ans
 pas
 p
 an
 pa
 secret
 name
 found
 confirm
 s
