Question

Write a program that does the following in C++

1 ) Write the following store data to a file (should be in main)

DC Tourism

Expenses 100.20

Revenue 200.50

Maryland Tourism

Expenses 150.33

Revenue 210.33

Virginia Tourism

Expenses 140.00

Revenue 230.00

2 ) Print the following heading: (should be in heading function)

Store name | Profit

[Note: use setw to make sure all your columns line up properly]

3 ) Read the store data for one store (should be in main)

4 ) Calculate the profit for the store (should be in getProfit function)

5 ) Print the store information in the following format (should be in printMessage function)

<Store name> | <Profit>

[Note: use setw to make sure all your columns line up properly]

6 ) Repeat steps 3-5 in an end of file loop [should be in main]

Your answer should look like this:

Store name Profit                                                                            

DC Tourism 100.30                                                                            

Maryland Tourism 60.00                                                                            

Virginia Tourism               90.00    

Functions you need

Function name | Parameters           | Return Type

heading | N/A                       | void

getProfit      | expenses,revenue | float

PrintMessage    | storeName1, profit | void
