Scenario:

Recognizing that different paint brands may necessitate specific equipment or expertise for proper application, Palette Perfection has opted to offer trained labor to execute painting projects according to the client's chosen brand. Consequently, the hourly labor charge will vary depending on the selected paint brand. Furthermore, to promote its service the company decided to provide a $5\%$ discount on the labor cost of the largest room if the total cost for the paint job exceeds $$700.$

Given these new specifications, adjustments must be made to the application to incorporate the labor charge per hour based on the paint brand, as well as to verify the total cost of the paint job and apply discounts as necessary.

The company has determined that for every $115$ square feet of wall space one gallon of paint and $8$ hours of labor will be required. For the available paint brands and the corresponding gallon prices and labor charge per hour check the following table.

As before, the application starts by asking the customer for their name and displaying a customized greeting message. All subsequent messages need to address the customers by their names. The application will ask the customer for the number of rooms to be painted. For each room, the application will first ask the customer to provide the total surface area in square feet of wall space to be painted and then display a list of paint brands that the customer can choose from. The application will then display a report for each room including the following details before reading in the details for the next room.

$$ The room surface area to be painted,

$$ The number of paint gallons required to paint the room.

$$ The price per gallon

$$ The cost for purchasing the paint

$$ The total number of hours of labor required for painting the room,

$$ The cost of labor for the paint job, and

$$ The overall cost of the painting job for the room.

When processing each room, the application needs to store some of the information displayed in the report to be able to calculate the discount when applicable. The information that is required to be stored is:

$$ The room surface area,

$$ The cost for purchasing the paint, and

$$ The cost of labor for the paint job

After processing the details for each room and storing the relevant information the application will print a summary report addressing the customer by their name including the details for all the rooms and total cost for the painting job over all rooms.

The application will then check if the customer is entitled to a discount and accordingly calculate the discount and print the total cost after the discount.

Before the application quits, it will issue a customized $$thank you$$ message to the customer. The application needs to validate all numeric values input by customer and in case of wrong input value or an input exception the application must give an error message and ask the customer to input the values again.
