Use the printout/dump to answer the questions and problems on the following worksheets

Worksheet 1

Worksheet 2

Once the two worksheets have been completed, put the answers on Blackboard.

Worksheet 1

Worksheet 1 can be found on Blackboard under Contents/Assignments. Click on the "Homework 2 Worksheet 1" link. There are 15 questions. Each one lists a field from the prewritten program and has two blanks that must be filled in: one for the address of the field and the other for the contents of the field. When you are ready to answer the questions, click on the "Continue" button. After the two blanks have been filled in, move to the next question by clicking on the > button to the right of the question. Once the last question has been answered, click on the "Save and Submit" button to submit the answers.

Note 1: The 15 questions do not have to be answered all at one time but once the "Save and Submit" button is clicked, whatever answers that were filled in will be submitted and it will not be possible to fix any of the answers. So make sure to double check the answers before clicking the button.

Note 2: Due to the limitations of Blackboard, it is highly likely that the order of the fields will be different from the order on the above HTML worksheet. Be sure to read the field name before giving an answer.

Worksheet 2

Worksheet 2 can be found on Blackboard under Contents/Assignments. Click on the "Homework 2 Worksheet 2" link. There is 1 question that has 10 blanks that must be filled in: one for each of the missing instructions. When you are ready to fill in the blanks, click on the "Continue" button. Once the last blank has been filled in, click on the "Save and Submit" button to submit the answers.
