This work is similar to task 1 and will be used to check your understanding and completion of classwork

Create a word document titled Your Name: Classwork Chapter 4 and Screensaver task. and save it

Read from Chapter 4 of the course text complete the following: Remember that this document will serve as your summary notes for this area so include a copy of the question in your answers.

All the questions from Exercise 4.3 pages 102 to 103. ( You don't need to do the extension elements, you can if you wish but they won't need to be submitted )

From Exercise 4.6 on page 117 do only Questions 1, 3, 4, 5, 6, 7, 8, 9, 10, 12.

From Exercise 4.7 on page 120 do Questions 12 to 15 ( ignore the additional word processor expectations in these questions and use this current document to record your answers ) Note that Word has re-sizable standard flowchart symbols in the insert shapes function.

From Exercise 4.8 do all the parts of question 2, ( Hint the words to Choose from are Pseudocode, Flowchart, Binary Selection and Multi-way Selection e.g. 2 a the full answer is Pseudocode Binary Selection ) then do question question 10 all parts and question 11. Ignore the instruction to produce a word document as you are already developing that in this assignment. Use the same Flowchart symbol inserts that you used in 4.7 ( Q15 )

From 4.9 do question 1 ( all parts ),  question 3 and 4,  then all of questions 12, 13 and 14.

Add your work for for you screen saver program write up at the end of this document.

Details for the Screen Saver Practical Task:

TASK DESCRIPTION:          You will be provided with some incomplete Qbasic programs designed to produce a ‘Screen Saver’ when executed. The task is to choose one as a ‘source’ program for analysis and modification. Identify the source programs design, including the variables used, the structures employed. Using the source program as a base design, produce a working program that correctly addresses the problem of a user terminated screen saver type package program. Include a flowchart and/or pseudocode for your developed alternative together with any other documentation used in the designing of the program. Produce a Data Dictionary for the variables and list the command words used ( and their syntax and function ). Follow recommended program modification best practice including the use of programmer guide rem statements and variable names.

OUTCOMES COVERED:     1.2  Describes and uses appropriate data types.

                                                             4.2  Investigates a structured approach in the design and implementation of a software solution.

                                                             4.3  Uses a variety of development approaches to generate solutions and distinguishes between them.

                                                             5.2  Uses and develops documentation to communicate software solutions to others.

                                                             6.2  Communicates with appropriate personnel throughout the software development process.

                                                             6.3  Designs and constructs software solutions with appropriate interfaces.

A sample write up is provided in the notes for the Module.
