Create a program named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a files size, you can create a System. 10.
