    What is the program suppose to do? What are you having trouble with? What results are you getting? What results are you expecting?

    you have to traverse your list and test values, then print the apropriate nodes
    unless you instansiate an additional list storing students with abscenses, then you could just do a straight print of that list only.

    Once the program is done, you should be able to enter peoples names and e-mail address that are in the class. From there you will enter the names of people that are present. From these two actions I need to find those who are absent. As of right now I have nothing, I have highlighted the part that I need help on in red.



    xviddivxoggmp3,
    Sounds good but I don't think that will work with the code I am trying to config. Thanks though!

    Looks like you need to traverse your enrolled list and for each element in that list, you then need to attempt to retrieve it from the present list. If you don't find a match, then you can do an insert into your absent list.

    If you were using a sorted STL container I would have just said to use the set_difference function.
