In previous chapters, you created applications for Marshalls Murals.

Now, modify the version of the MarshallsRevenue program created in Chapter 5 so that after mural data entry is complete, the user is prompted for the appropriate number of customer names for both the interior and exterior murals and a code for each that indicates the mural style:

• L for landscape
• S for seascape
• A for abstract
• C for childrens
• O for other

When a code is invalid, reprompt the user for a valid code continuously. For example, if Y is input, output Y is not a valid code, and reprompt the user until a valid code is entered.

After data entry is complete, display a count of each type of mural. For example the output should be in the following format with the correct number next to each mural type:

The interior murals scheduled are: Landscape 1 Seascape 2 Abstract 1 Children's 3 Other 9 The exterior murals scheduled are: Landscape 4 Seascape 0 Abstract 2 Children's 4 Other 0

Then, continuously prompt the user for a mural style code until the user enters a sentinel value (the uppercase character Z should be used as the sentinel value).

With each code entry, display a list of all the customers with that code and whether their mural is interior or exterior. If the requested code is invalid, display an appropriate message and reprompt the user. For example if L is input, the ouput might be:

Customers ordering Landscape murals are: Katie Interior Jake Exterior

If U is entered, the output should be U is not a valid code.
