Code for a "vidbox" prototypes not functions, writings and reading from a file?

[kjblkblt]

The assignments has me updating files throughout the program to keep current records. Also while applying discounts and doing some error checking. I am not allowed to utilize functions at this time but I can utilize prototypes (I'm not even sure of the difference). I am having several issues with the program it will not compile at all (I am utilizing VS 2013). The probelms seem to revolve around my use of prototypes, passing information back anfd forth between them, the file writing, reading, opening ect., and my switch statement. At this point there are so many errors I'm a littl overwhelmed and I'm not doen with the program yet. Thank you for any and all help!!

the file dayin00.dat needs to have 2 different numbers on 2 seperate lines the current number of videos in the box and the current amount of $ in the box.

the file current11.dat should have a line written to it every time a transaction is completed, to include the member ID of the person, the number of DVD's taken or returned, the amt of $ that was added, the overall count of DVD's, and the total amount of $ in the vidbox.

dayout99.dat should have the current amount of $ in the machine and the amount of DVD's in the unit but only when "Close down" is chosen from the menu.
