One solution is to add another structure used to make the association between a member and a video.

In the loan file, you would have one line per member-video association; there would be no video association in the member structure, nor member association in the video structure.

With this solution, the member file will be changed only when a new member is added, or when a member is removed. The same way, the video file will be changed only when a new file will be added, or when a file will be removed from the inventory.

Hope it helps!
