Getting string info from txt file, possible?

[cw2395]

Howdy,

I am doing a project for data mining, below I have modified some code to create item frequency and support data calculations, but I wanted to see if I could draw in all the original string information for the RawTransactions from a txt file.

Say I had all of this in a file on desktop in a new folder and a .txt file in the folder named "info", would there be a way to draw all of it from that file?

Thanks for any help!

If you feel that you need to post that much code then you clearly haven't given the problem enough thought. I can't speak for others but, personally, I'm not even going to bother reading unless you narrow it down to just the relevant code.

 

[cw2395]

Is that better?
My apologies, I was unaware if it would be necessary to see it as a whole or not, this is really my first go around asking for help on a forum, usually I ask in person but classes do not start back until the 6th.

Thank you for the information, I will edit further as requested as well.

 

[jmcilhinney]

The answer is yes, you can read data from a text file. Storing data in CSV files is very common and fixed-width text files also common but less so.

 

[cw2395]

Would that be called parsing information or storing values into an array?
Mind giving me a few more key words for the subject so I can google and give it a shot myself?

I by no means want the direct code or solution, but I would like to be pointed where to look if you dont mind

And thank you for the quick replies by the way.

I am new to coding, so I ask this question out of interest, not rudness,

Is this line bad code:

int N = rawItems.Length; // total number of items

why not just use

int totalNumberOfItems = rawItems.Length;

and leave out the comment.

Use meaningful names, and only comment where it is needed

 

[cw2395]

I agree with you actually!
Thank you for the insight

I am quite new to it all myself as well.
