OK, you've managed to dump your assignment on us, what do you actually need help with?
We're not here to do your work for you.

I just felt stuck because I did give it a try. Following is the implementation I tried for Book.cpp.
However, I wanted to know how to make this work without using an array if there are more than 1 book that is going to be read from the file.

Please edit your post(s) to put [code][/code] tags around the code.
Your << and >> operators should only deal with ONE book (the one passed as a parameter), not an array of books.
Your << and >> operators should only deal with ONE book (the one passed as a parameter), not an array of books.
The thing is, it would read a file and store the books.
If the >> operator only read the first book from a file of books, how would I be able to read the next book?
