Programming in C# Write a program that shows the formatted retail price of shirts when there is a 15% markdown. Test the program by performing a compiletime initialization with an item labeled Open Collar Running Shirt, which has a wholesale price of $41.00. How much savings is expected with the markdown? Display appropriately labeled retail and markdown values for the shirt. Once you get that running, go back into your source code, add lines of code that will reassign the memory locations values for a Razorback T-Shirt, which has a retail price of $36.00. Add additional lines of code, which will display the new items information along with the previous item. What happens if the markdown goes to 20% or 10%?
