Question

an airline's reservation system Suppose you are tasked with building (a) To simplify the situation, let's say that this system just needs to keep track of flights, passengers, and airports. Describe how you would represent these objects in your program (b) Describe several functions that would need to be defined (for example, you'll want a function which takes a flight and returns the number of available seats remaining) Note: this is a code planning exercise; there is no actual code to write.

Answer 1

Question A.
We create class for each object. Flight class will contain information about source and destination airports. Also number of passengers, free seats and time needed for the flight. Airport class will contain two list of flights, one for arrivals and second for departures. It will have timetables for the flight too. Passenger class will contain his ID, and list of ticket. Each ticket will have information about flight, destination and starting airports, time for departure and arrival.

Question B.
Function to get number of free seats left: flight class will have such function, it will check total number of passengers and total seats in plane and will calculate and return number of free seats left.
Function to get cheapest flight from one airport to another: Airport class will have this function. It will get another airport as argument and using shortest path algorithms it will find cheapest flight to this airport, probably including stopovers.
