Please read the following instructions carefully before submitting assignment. It should be clear that your assignment will not get any credit if:

  • The assignment is submitted after due date.
  • The submitted assignment does not open or file is corrupt.
  • Assignment is copied(partial or full) from any source (websites, forums, students, etc)


Note: You have to upload only .cpp file. Assignment in any other format (extension) will not be accepted and will be awarded with zero marks. For example, if you submit code in .doc (Word document) or .txt files, no reward will be given in any case.





The objective of this assignment is to provide hands on experience of:


  • Structures
  • Dynamic Memory allocation in C/C++
  • String Manipulation Functions
  • File Handling





  • Code should be properly indented and well commented.
  • Follow C/C++ rules while writing variable names, function names etc
  • Use only dev-C++ for this assignment.
  • Use appropriate C/C++ structure i.e. if-else; switch statement etc to get inputs from user where required (Marks will be deducted if inappropriate structure will be used).









Problem Statement:  Flight Reservation System


Write a program for Flight Reservation System which reserves the tickets for passengers of an Air Line according to their requirements. 


Detailed Description:


In the program, you are required to make a structure with name 'Reservation' and following are the data members of structure.


ñ  Passenger Name

ñ  Passenger Address

ñ  Date of flight

ñ  Destination to travel

ñ  Flight No

ñ  Seat No


In the main() function, create of variable of type Reservation. The variable of type Reservation should be created dynamically using memory allocation function. After that, create following user defined function as discussed below:


GetData(), this function will set the values of above created structure variable according to the inputs taken from user. It will prompt user to enter required information for the, Passenger Name, Passenger Address, Destination, Date of flight. User will be provided three options for the destination that is: Karachi, Lahore and Peshawar.


Assigning Flight No and Seat No:


The user will chose one of three destinations and program will assign an appropriate Flight No for the passenger. The Flight No will be assigned as below:


         Destination                    Flight No.

          Karachi                          201

          Peshawar                         233

          Lahore                           241


After Assigning Flight No, the Seat No. will be assigned randomly which can be any number from 0 to 200.


After assigning the values for the above created variable of Reservation structure, the structure will be passed to another user defined function WriteData() for writing it to the file.



In the function WriteData(), you are required to create a new text file name “data.txt” in same folder/directory where you have saved your .cpp file. Open this file by using file handling functions and then write all Reservation information in that file.


At the end, read all the data from file by creating a function named ReadData() and display the file contents on the screen.



Points To Remember:


Following points should be kept in mind and handled accordingly, otherwise marks will be deducted. 


ñ  Reading and writing from text file, must be done with standard file handling functions provided in handouts. 

ñ  All data members must be declared and initialized with appropriate data type.

ñ  Exceptional cases must be kept in mind and handled accordingly while taking input from user.

ñ   User must be prompted if there is any error while:


◦   Creating a file.

◦   Opening a file for reading/ writing.
