[zain mahmood]

Instructions:   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.     Objectives:   The objective of this assignment is to provide hands on experience of:   Classes Function Overloading Dynamic Memory allocation in C/C++ String Manipulation Functions File Handling Stream Manipulators     Guidelines:   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:  Airline Fare System Write a program for air fare System which will calculate fare on already reserved ticket.                                                  Detailed Description:   In the program, you are required to make a class with name 'airfare' and following are the data members of class airfare.   ñ  Seat type ñ  Price ñ  Tax ñ  Airline charges   In the main () function, create a constructor of class to initialize the class data members. Class must have a destructor. Create following user defined function as discussed below along with class constructors and destructor:   GetData(), this function will take the input for seat type variable from the user and will set the ticket price according to the input taken from user. The function GetData() will prompt user to enter required information for seat type.   Seat Type: User can select one of the Seat type:   1. First Class Seat 2. Business Class Seat 3. Economy Class Seat   The function GetData() will also read the data from file named data.txt ( created in assignment no 3 ) to read the destination and then assigns the price for the given destination.     Price: Price will be calculated on the basis of following information:   1- Fare type 2- Destination (Desire destination information will be read from the file “data.txt” )   The price will be assigned according to the table given below:         Seat Type Destination Ticket Price Economy Class Karachi 3000 Economy Class Peshawar                         2500 Economy Class Lahore 4000 Business Class Karachi 5000 Business Class Peshawar                          4500 Business Class Lahore 6000 First Class Karachi 7000 First Class Peshawar                         7000 First Class Lahore 7000     Airline charges: All airlines will charge 15% of ticket price extra to the all fare types along with the tax.     Class should have a user-defined function named CalculateTax() to calculate the tax according to seat type and ticket price.   Tax calculation will be done as below:   If seat type is First class then tax will be 30% of ticket price If seat type is Business class then tax will be 20% of ticket price If seat type if Economy class then tax will be 10%  of ticket price     Calculateprice(), this member function will calculate price of already reserved ticket and will display total fare on the screen. Price calculation will add above calculated tax, airline charges to the actual ticket price according to following information.   Fare = Airline Charges + Tax + Ticket Price     In the function WriteData(), you are required to create a new text file name “fare.txt” in same folder/directory where you have saved your .cpp file. Open this file by using file handling functions and then write all air fare information in that file in following format.   ------------------------------------------------------------------------ Name | Address| Date | Destination | Flight. No | Seat. No | Fare ------------------------------------------------------------------------. . . . . . . ------------------------------------------------------------------------   Required information of Name, Address, Date, Destination, Flight No, Seat No, should be taken from assignment no 3 output file.     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.
