Part Two $(20$ pts$.)$

Modify the StringStuff DesktopApplication You Just Did

Start with your completed StringStuff Calculator Application from the exercise above. Add a

method that receives the word entered as an argument and returns a string with a $ added

after each character. For example if the word entered is Hello, the string returned is

H$e $$1$$$1$$$0$$$.$

Add a label that says Dollar Signs and a label next to it for outputting the string with the

added dollar signs. Your Transform button event handler should call your new method and

output the string with the dollar signs.

Once you finished all of the above and tested it to make sure that it works properly, paste a

copy of your C# source code showing your entire Transform button click event handler and

your new method. Also paste a screen print of the application running after the word Hello

has been entered and the Transform button selected. My code is : namespace StringStuffApp
