Calculator Programming Project Updates

Introduction

In this programming project you will improve your Calculator page by displaying its output right on the page, rather than producing alert messages. You will also include a last modified date on the page.

Updating the Calculator program:

1. As you did for your Mad Libs program, modify your Calculator to write the output to the web page instead of to alert messages. Create an empty paragraph (<p>) or division (<div>) element between two horizontal rules at the bottom of the page, and write the Calculator results to that new element.

   In this case, repeatedly clicking the Calculator button should cause the previous results to disappear and be replaced by new results. (This is different from the Mad Libs case, where new Mad Libs stories should be appended to existing ones.)

2. Add a last modification date to the end of the Calculator web page, just as you did for the Mad Libs page.

Polish & Publish your Calculator program:

1. Polish:
   • Add formatting tags, as appropriate.
   • Make sure your HTML source file is readable also, and includes all appropriate comments.
   • Make sure that you have updated the "Author:" and "With assistance from:" comments at the top of your source file.
2. Publish:
   • Upload your modified web page to the comp105.cs.kzoo.edu server and test that it works there. If you worked in a team, each member of your group should do this, so each of you has a link to your calculator page. After the link, list your teammates in parentheses; for example, "Calculator Program (Harry, Ron, and Hermione)".
   • Test that the modifications show up on the server by clicking on the link from your home page there. (Make sure that your browser is looking at the page on comp105.cs.kzoo.edu, not your local version.)
