C++ Project

You have learned that programs can make simple choices and they never get tired of repeating things. You plan to write a simple program, Airfare.cpp, which repeatedly asks the user to enter ticket information and then calculates the total price for all the tickets entered.

The price of a ticket depends on the destination. The program has information on these destinations:

Destination	One-way Price
Boston	$ 350.00
London	$ 600.00
Paris	$ 700.00
Tokyo	$ 800.00

If a ticket is requested to some other destination, the program informs the user that no tickets are available to that destination. The user can enter the city names as given or in all lower case.

The round trip price is the one-way price multiplied by 1.6. There is a 20% discount for students. The user enters this information by entering the letter Y or y to mean yes and N or n to mean no.

When the user enters the word Done or done when asked for the destination, the program outputs the total number of tickets and their total price and exits. A few sample runs are given below:
