Problem: When you use Visual Studio you can open various sorts of files, edit them, and then save them. Text files are shown as text and bitmap files are shown as images. We might suppose that there is a FileOpen(CString filename) method. Some of this code will act the same no matter what kind of file you open, but part of the code will act differently depending on the kind of file. Describe how this might be accomplished by using the Template Method. Draw a UML diagram and write out some very rough code, simply using made-up names for the functions you use.
