But, yes you could store them in a file!

But your program doesn't do that. And later on you want to compare those values to some other values, and it doesn't work... because you don't have access to them anymore.

So, let's summarize: You generate values, but you don't store them. You read data from a while, but you don't do anything with it. So there's are at least two steps missing: extracting the columns from the read data, and make the generated data available to the program itself.

When you've done these two steps, maybe you'll get unstuck.

Also please notice that your description of what you want to do is incomplete: you write you want to compare values, but you never mentioned what you want to do with the result of the comparison. Store it? count it? make funny bit masks? destroy the world?
