Overview: The supplied data file2, music.dat and music2.dat contains a listing of the bestselling song recordings, released as singles, of all time. The assignment is to complete two programs that will first read the song information, which includes song sales, and compute revenue and profit using additional information provided below. Each line of the data file will contain the artists name, the song name, the year released, the total sales (in millions) and medium that the song was released on. The medium will either be physical, which includes records and CDs or digital, i.e. downloads. The file format is as follows: Artist Song_Title Year Sales Medium

To simplify file parsing, multiple words in an artist name and/or song title are combined into one string with an underbar character separating each word. The programs will use this information to compute the gross revenue and the profit generated by each song using the following information. The cost to produce a song on physical media is taken to be 75 cents while the cost for a digitally released song is 25 cents. The sale prices are $1.50 for the physical media and 99 cents for downloads. (Use variables to set fixed values.) The final step will be to output a neatly formatted list of the song information, including revenue, and profit, sorted by the profit from highest to lowest.

What you need to do:

1. Prompt the user for the name of a data file o Exit gracefully if there is a problem finding or opening the data file

2. Read the information from the data file into the parallel arrays. You can assume that if the file contains data, it is well formatted. But you should: o Keep a count of the number of members read (Detect the end of the file!) o Stop reading if the number of entries in the file is greater than the array size (ignore the extra entries)

3. Output a cleanly formatted table of all data read

4. Compute the totals (revenue and profit) for each song and store them in the extra supplied arrays. Use variables to set fixed values!

5. Output all data again, but include the computed revenue and profit calculated in step 4.

6. Sort all information, including revenue and profit, for each song from high to low, based on the profit (i.e. last column).

7. Output the sorted results including all information as in step 5 (use the same output function

The output should be identical. The one, significant, difference is that this program uses an array of structs to store and process the data rather than parallel arrays
