The objective is to write the program that can help you process the database. Your program should be able to (1) display the database in a readable format, (2) show flights that depart from a given city, (3) find the flight with the best distance to price ratio and show it together with the ratio. Note: you can assume that your input file has no more than 100 flights stored, so you can create an array of flights with 100 elements in it and then use only as many as you read from the file.
