Help with Structures

JoeMurda (12)
Hey everyone I need help with structures. In particular this problem I am having. I'm working on a project where take an in_file and compute the average and display the highest average and its number. I compute the average by taking laps(numbers) if one of those numbers is negative instead of displaying the average it should "DQ"(disqualified. Then it must display how many were DQ and how many were qualified. This is my code for far. Any help would be appreciated. Thanks

I have looked at my errors and improved the code.
