I didn't read all of your code... mainly because you need to use the code header files(button on the right looks like <>). I can tell you right now by looking at your errors though that:
'record::id_number', 'record::type', 'record::price', 'record::num_in_stock', 'record::title', 'record::author_artist', 'record::year'
all need to be in the PUBLIC part of your class, not in the PRIVATE.

Private is for only the class to use and is never called anywhere outside of the class. Public is called outside of the class(usually in the program)

You might consider making void read_all_records a friend of the class, although the more usual thing to do would be to define a function that reads one record as a friend of the class and use that within read_all_records. Or you could read the values into intermediary variables and then use the setter functions.


In num_in_inventory_of_type you just need to use the appropriate getter and setter functions.
