Ugg, I do not know why I keep getting errors when I run this project. It ran perfectly before. If anyone can take a look and tell me why I get these errors, I would really appreciate it. Thanks.
I'm going to post the files one by one, then the errors at the very bottom. This is a long multiple file project so anyone who is willing
to help me, you rock and thank you so much.
Code:// sale.h -- header file for the Sale class // // An object of type Sale will store information about a single sale. // The variable "item" stores the type of item being sold (one of the four // items in the enumerated type ItemType). Books, music, and software are // the types of items sold. CREDIT stands for store credit, which incurs // a negative monetary charge. // The variable "price" stores the base price of the item // The variable "tax" is used to store the 7% sales tax // The variable "total" is used to store the final charge (price + tax) enum ItemType {BOOK, DVD, SOFTWARE, CREDIT}; class Sale { public: Sale(); // default constructor, // sets numerical member data to 0 void MakeSale(ItemType x, double amt); // the MakeSale function loads data into the Sale object. The // item and price are passed in. Compute tax and total. // (For store credits, tax is 0). ItemType Item(); // Returns the type of item in the sale double Price(); // Returns the price of the sale double Tax(); // Returns the amount of tax on the sale double Total(); // Returns the total price of the sale void Display(); // outputs sale info (described below) // for the Display function, output the sale item, the price, the tax, // and the total (all on one line).

These are the errors I get.
