Hey man Sorry for the untidy question. So I have single word strings in both files A and B and that too in a sorted manner. Like A will have bin hye B will have something like bin den mig So C shouldnt have all those things from A which are matched in B.. C should be den mig as bin was matched from A. This is no homework but for some work.Really will appreciate if you can provide the code for your solution: "To solve a problem like this, I would generally read in the contents of file A into a hash, since you just want to use those words as a lookup. Then I would open files B and C, step through the contents of file B a line at a time, and, whenever the line of B contains a word in my hash, drop it on the floor -- otherwise, write that line to file C. I don't think that opening the file handles inside your loop is a good idea. "
