Create a program called TreeMonster (sample user interface below) that lets a nursery figure out the total number of trees at four locations. A nursery worker will use the program's textboxes to enter the number of trees at each location, then he/she can click the "Add Them Up" button to get the sum. The image below is just a sample -- feel free to make your app look nicer than the example GUI shown. Make sure you test your program with several different data values, then turn in output showing that it adds properly. To get started in Visual Studio, click File->Project->C#- >Windows Forms App (.NET Framework). Tree Monster Enter the number of trees at each location Location 1 Location 2 Location 3 1 Location 4 Add Them Up! You have xxx total trees
