Problem
1. Create a dynamic Web site that functions like a calculator. Add features for addition, subtraction, multiplication, division, modulation, and so on.
2. Create a Web application that enables the user to enter first name, last name, and e-mail address. Accept those values and store them in a text file. Allow the user to input the path where the file should be stored. After retrieving the values from the user, display on the Web page both the full file path (including the name of the file) and all values stored in the file. Confirm that the values are written to the file.
