Of all the common file formats, the CSV is probably the oldest one still in use. It’s a plain text file, so the formatted data appears is readable by humans: Each line is a record. Each field is separated by a single comma.

\nOther plain text file formats are popular today, including XML and JSON, but CSV is easy to read and write in C without having to use external libraries.<\/p>\n
Right-click this link<\/a> to download a typical CSV file. This one stores dates and temperatures from this year’s brutal winter in my home town. The data is formatted as follows:<\/p>\n When you know what the fields represent, the CSV file makes sense; otherwise it’s just a list of meaningless numbers. In this case, the format uses numeric values (no strings). Some values are integers, others real numbers (floats). Strings in a CSV file are usually enclosed in double quotes, though this practice isn’t consistent. Regardless, for this month’s Exercise, the data are all numbers.<\/p>\n Your task is to create code that reads the CSV file, This task portends a more complex program that I offer as next month’s Exercise. Until then, on your own, write the code to process the CSV file.<\/p>\n (Click here<\/a> to view my solution, but please try the exercise on your own before you see what I did.)<\/p>\n","protected":false},"excerpt":{"rendered":" Write code that fetches data from this common, plain text, file format.
