Right now the code does not compile because I am receiving an error on the line that says if (bt = myBkStore.inStock(title, y)) because of incompatible types. I have a function called inStock, but I am unsure of how to call this function. The problem that I am having is checking to see if the book title that the user enters in is already in stock. When the user selects option 1, it asks the user to enter the book title, it then checks if the books is already in stock. Option 1 is to add more books to the stock. Currently, the one I am working on is option 1. The program gives the user 6 different options for them to select from. I am writing a bookstore program for homework.
