Answer 8

How does your program work? Describe what would occur when the finished program is run.

It sounds like a couple things your program needs to do include:
-read in a text file to store details of gadgets
-allow a user to create/modify gadgets

Without knowing what kind of material you're learning right now it's difficult to say what is the best option for you. To read in a file, you need to have a function that knows how to read the text file and parse it for the formatted data. Depending on the structure of your program, each line could be a separate gadget, so you need to instantiate a new gadget and define it as you're reading each line.

Really though, what you're asking for is too vague and requires others to do the guessing for you so you might want to clarify the specifics.
