please help with reading/converting text file

[morgancassiday]

Hello, I'm having a lot of trouble with this program. I need to extract things from lines in file. for example one of the lines would be:
2013-05-07-1430, DTW, 150SW, FL330, Delta123
with this I would need to convert the first section to a date and time like "May 7, 2013" "2:30pm" then I would have to convert DTW to "Detroit Metro Airport", then convert 150SW to "150 miles southwest", then FL330 to "33,000 feet" and Delta123 to "Delta 123". I'm having problems extracting the portions of this file. I'm used to grabbing information within the commas but not within letters and numbers. I could use some help on how to do that. thank you


Write a C++ program to process air traffic control data stored in a comma-delimited file. The data relates to incidents of severe turbulence and you wish to create a plain text summary report for the file.

You will not know how many lines of data will be in the file. The format for the file will be:


{date},{airportcode},{distance from city},{flightlevel},{flightID}

An example data line for the file could be:


2013-05-07-1430,DTW,150SW,FL330,Delta123

The format for the date/time will always be exactly 15 characters (yyyy-mm-dd-hhmm).

CORRECTION:
The airport code will always be precisely three characters. The distance string will of course will vary,but the number will always be a one or two-digit integer followed by a two-character compass direction (N=north, NE-northeast, E=east, and so on). The altitude is presented as a coded number requiring the digits after the “FL” to be extracted. Add two zeroes to this value (along with a comma) to convert the flight altitude to feet.. Finally, the aircraft identifier will vary in the number of characters but will always be the last field in the line.

The provided file flights.txt will vary in the number of flight data lines. Be sure to use an end-of-file loop to drive the processing of your program. Each line of the input file includes one flight, time, and location. For each line of input, write an output message that can be printed:

Given the example above, the with output then:


Flight: Delta 123
Date: May 7, 2013
Time: 2:30 pm
Location: 150 miles southwest of Detroit Metropolitan Airport
Altitude: 33,000 feet

Your output should then be a list of these summaries, one for each observation. One additional data file will be required to allow you to convert the airport code to the airport name. Data file miairports.txt includes many actual airport identifiers and names. Your program will need to read this file into an array so that it can be searched as you process each line of the primary input file.


The program is presented in modular form using functions. You should continue this design with functions for the new features you are adding.
