I cannot get this thing to work. Below is what i have so far. I have tried different ways to get my output,by following the instructions, similiar to the sample output, but to no avail. I must be doing somethinig wrong with the While Loop, Array objects...I don't know. If any one could help me fill the GAPs, please. Also, if possible, in-line comments for clarifaction so it sinks in. If so, you are a rock star. SORRY FOR THE LENGTH.I KNOW.

This application will declare an enumerated type DessertType, which will be used in a switch statement to determine which action needs to be taken.

Depending on the DessertType, the program should prompt for specific details in order to calculate the price for each item.

CANDY

Prompt for Name, Number of Pounds, Price per Pound

COOKIE

Prompt for Name, Number of Cookies, Price per Dozen

ICE CREAM

Prompt for Name, Number of Scoops, Price per Scoop

SUNDAE

Prompt for Name, Number of Scoops, Price per Scoop, Number of Toppings and the Price per Topping

The application should be called DessertShop, which will prompt the user for items to purchase. This application will prompt the user for the name of the product. If no name is entered, the application will calculate the total cost of items entered.

The application will define four arrays for each DessertItem, which can store up to 10 items each.

Each derived class will contain a static variable which will store the total DessertItem cost and total DessertItem tax (if applicable) for that specific DessertType. The CANDY and COOKIE dessert types are taxable at 7%. The ICE CREAM and SUNDAY dessert types are non-taxable.

The DessertItem superclass will also contain a total cost and total tax static variable that will be shared between all items that were derived from that superclass.

Upon successfully entering an item, the total cost and total tax of that DessertItem will be updated, along with the total cost and total tax for all items. The application should check an item to determine if that item has already been entered, except for Sundaes. If the item has already been entered, the existing information should be updated to include the new items.

Upon entering all items, the application should print out a summary of the DessertItems, along with the count, the cost and tax. (See Sample Output)

Sample Output

CANDY [2] Cost: $4.52 Tax: $0.32

COOKIES [24] Cost: $12.96 Tax: $0.91

ICE CREAM [1] Cost: $3.99

SUNDAE [4] Cost: $8.87

---- -------- -----

Subtotals [31] $30.34 $1.23

========

Total $31.57

After the total has been displayed, the application will prompt the user to see if they would like to save the receipt to a file. If yes, the application should prompt the user for the file name they would like to write the receipt to. The application should then open a text file and output the receipt information to the output file.
