Hi everyone! I've been working on a C++ project to make a Library database program that involves storing a list of both users and books with their respective information, and allowing the act of checking out/checking in a book. I got both lists made up in vectors, and they work fine, but I can't figure out how to change the element in the vector item I've assigned "Status" for CheckOut. I'd appreciate any help on this, I've been working at this since Sunday and haven't been able to figure it out. The code is posted below!
The specific place I'm looking to do it is in the CheckOut function of the LibraryDatabaseUI class, but all my attempts so far have failed to change the original status. Thanks again for any help!
