Unit 2 Assignment Instructions
In this unit you will complete the coding exercises before starting the coding Projects.
Review the detailed instructions and rubrics before starting your Assignments.
Submission Instructions
You will submit the following:
.cs files for C#
.java files for Java
.php and/or .js files for Web Development
Additionally, in a Word document, paste a screenshot of the output for each exercise.
You will be submitting three code files, one for each exercise (.cs, .java, .php or .js) and
one Word document in a zipped folder.
Zip these four files into a zipped folder and submit the one zipped folder.
Naming Your Files and Zip Folder
The code files should be saved as:
IT213_YourLastName_UnitX_ExerciseX_Language.
The word document should be saved as: IT213_YourLastName_UnitX_Screenshots
The zip folder should be saved as: IT213_YourLastName_UnitX_ZIP
Unit 2 Coding Exercises: Coding Exercises
You must complete the following coding exercises before starting the coding Projects.
By completing these exercises you will be better prepared for the Assignment.
Note: If your language of choice is Web Development, you will need to complete the
exercises in both PHP and JavaScript.
2-1.Type the following accurate code in the language of your choice. If there are errors, use the
accurate code to check against the code that you entered and fix any issues. Run the
completed code.
