Question

c#

In Chapter 2, you created an interactive application named MarshallsRevenue. The program prompts a user for the number of interior and exterior murals scheduled to be painted during the next month by Marshall’s Murals.

Next, the programs compute the expected revenue for each type of mural when interior murals cost $500 each and exterior murals cost $750 each. The application also displays the total expected revenue and a statement that indicates whether more interior murals are scheduled than exterior ones.

Now, modify the application to accept a numeric value for the month being scheduled and to modify the pricing as follows:

• Because of uncertain weather conditions, exterior murals cannot be painted in December through February, so change the number of exterior murals to 0 for those months.

• Marshall prefers to paint exterior murals in April, May, September, and October. To encourage business, he charges only $699 for an exterior mural during those months. Murals in other months continue to cost $750.

• Marshall prefers to paint interior murals in July and August, so he charges only $450 for an interior mural during those months. Murals in other months continue to cost $500

revenueInterior = numInterior * INTERIOR_PRICE;
revenueExterior = numExterior * EXTERIOR_PRICE;
total = revenueInterior + revenueExterior;
isInteriorGreater = numInterior > numExterior;
WriteLine("{0} interior murals are scheduled at {1} each for a total of {2}",
numInterior, INTERIOR_PRICE.ToString("C"), revenueInterior.ToString("C"));
WriteLine("{0} exterior murals are scheduled at {1} each for a total of {2}",
numExterior, EXTERIOR_PRICE.ToString("C"), revenueExterior.ToString("C"));
WriteLine("Total revenue expected is {0}", total.ToString("C"));
WriteLine("It is {0} that there are more interior murals scheduled than exterior ones.", isInteriorGreater);
}
