C$++$ Case problem $10\mathrm{.}2$Previously$,$ you created a Mural class for Marshall$$s Murals. The class holds a customer$$s name, a mural code, and a description. Now, add a field named Price to the Mural class that holds a price.

Now, extend the Mural class in your code to create subclasses named InteriorMural and ExteriorMural, and place statements that determine a mural$$s price within these classes. $($A mural$$s price depends on the month, as described in the case problem in Chapter $9$ of your book.$)$

The constructor for the subclasses should have one parameter for the month the mural is scheduled.

Also create ToString$()$ methods for these subclasses that return a string containing all the pertinent data for a mural. The string should be returned in the following format $($shown for one exterior and one interior mural$)$:

Exterior, Seascape mural for Customer: Steve Price $$699\mathrm{.}00$ Interior, Landscape mural for Customer: Joe Price $$500\mathrm{.}00$

In order to prepend the $ to currency values, the program will need to use the CultureInfo.GetCultureInfo method. In order to do this, include the statement using System.Globalization; at the top of your program and format the output statements as follows: WriteLine$("$This is an example: $\{0\}",$ value.ToString$("$C$",$ CultureInfo.GetCultureInfo$("$en$-$US$")))$;
