| | I think what you want to do is to load a text file into a single linked-list data structure, and then offer the user to sort the list by certain attributes; in the case you speak of, by user i.d. So let's break this mother down step by step. Let's … |

 | On your intended last iteration, line #12 will test true; however, line #14 will perform one additional calculation that you probably don't want it to do and will subsequently print the result (line #15.) One solution could be to change your loop to a do/while so the evaluation to continue … |
