In previous chapters, you continued to modify the MarshallsRevenue program. Now, modify the program so that the major functions appear in the following individual methods:

• GetMonth - This method prompts for and returns the month
• GetNumMurals - This method prompts for and returns the number of murals scheduled and is called twice -- once for interior murals and once for exterior murals
• ComputeRevenue - This method accepts the number of interior and exterior murals scheduled, accepts the month they are scheduled, displays the interior and exterior prices, and then returns the total expected revenue
• DataEntry - This method fills an array with customer names and mural codes and is called twice -- once to fill the array of interior murals and once to fill the array of exterior murals
• GetSelectedMurals - This method continuously prompts for mural codes and displays jobs of the corresponding type until a sentinel value is entered.

code i have so far
