The first part of ETL is extraction. The filename of a text file will be passed to your program via the com mand line. The data contained in that file is to be read into memory (i.e., extracted). Your program will be compiled and run on Eustis using the following commands: o etl hw1et, l c gCC /etl input File It is entirely possible that the input file either does not exist or is not where it is supposed to be. In such an event, your program should print an error message to STDERR that indicates which file is missing, then your program should exit safely. Use the following format for your error message fileName should display the actual name of the missing file): etl ERROR: File fileName not found The input file is in CSV (comma separated values) format where each line contains the data for one airport and the fields are as printed below. Note that these fields vary in size and content. Some fields may even be empty. Also note that the data for some of the fields are a melange of types. Specifically, the FAA Site Number and both latitude and longitude contain numbers, punctuation, and text. For this assignment, treat all input data as character data
