Project Instructions

Flowchart and Pseudocode

The Computer Science Project is a software development project in which you will have an opportunity to demonstrate your programming skills and understanding of the relationship between the different areas of solution development.

You need to provide the following outputs:

Subject Class Teacher

Grade 8

Mr. Zuko / Mrs Salam

A report where you (Basic Project)

o discuss the research/investigation done regarding the project

o provide a brief description of the purpose and scope of your project

o provide analysis of a possible solution

A document outlining the system design using Flowchart (Intermediate Project)

A document outlining the system design using Pseudocode (Advanced Project)

TASKS

You may use any of the following application programs (not limited to) to complete your project: o Any word processor program like MS Word o Any Desktop Publisher like MS Publisher or Adobe PageMaker o Any presentation program like MS PowerPoint o Any drawing/painting program like MS Paint or CorelDraw o Any Flowchart drawing software like SmartDraw or RAPTOR.

While printing, use Arial or Times New Roman font with font size 11 points for the normal body text and 14 points for any sub-headings.

Use A4 sheets for printing. Internet access to find data and information Access/Exposure to similar existing system such as ATM machine, guessing game, quiz etc

depending on the chosen topic

BASIC PROJECT

The purpose of Phase 1 is to determine what should be done and what the user requirements are:

Research/investigate the topic/scenario/the potential user(s) to gather facts about the nature of the system you intend to produce.

Write a description of the existing system (i.e. your topic) The description of the problem - Explain what you are asked to do in this project. The description of the method of solution - Write in detail how you are going to solve this

problem (Include all the possible solutions). In this section, you must describe all the possible criteria while checking a condition that could

be used in your solution.

See Assessment tool for more instructions

If you successfully complete the `Basic Project' criteria the maximum mark you can be awarded is 5% out of the possible 10%.

INTERMEDIATE PROJECT

The aim is to

Determine HOW you will go about solving the problem and plan the detail. Produce a plan showing a high level overview of how the solution will be constructed. Use

Flowcharts. The plan must show all the main blocks within the proposed solution.

Instructions:

Design a Flowchart for the whole system. All necessary requirements should be listed in logical order. The Flowchart should be clear, neat and easy to follow. The usual direction of the flow of procedure is from left to right or top to bottom. Use correct symbol for each step. Only one flow line should come from a symbol, unless it is a decision symbol. It should the correct flow of data from/to each section of the diagram Check your Flowchart with suitable test data.

Example of a Flowchart:

See Assessment tool for more instructions If you successfully complete the `Basic Project' and the `Intermediate Project' criteria, the maximum mark you can be awarded is 7.5% out of the possible 10% ADVANCED PROJECT The aim is to implement your design in intermediate phase (Flowchart) using Pseudocode. Write algorithm using Pseudocode to implement the algorithm you presented in phase 2. Use correct keyword where necessary. See Assessment tool for more instructions If you successfully complete the `Basic Project', `Intermediate Project' and `Advanced Project' criteria, you will be awarded the full 10%.

List of Topics:

1. ATM transaction: Develop a system that simulates ATM transactions e.g. inputting and validating pin/password, checking of balance etc. (HINT: Use variables, constants or arrays to store account details such pin/password, account number or balance etc.).

2. Guessing game: Develop a system that will allow end-user to guess a number/word/letter. Provide the user with limited chances to guess (e.g. give the user 5 chances to guess a number). When the user guesses correctly, output a congratulatory message otherwise output an appropriate message with the secrete number/letter/word after all attempts. You may wish to warn the user when the user when the guess is far, close, bigger or smaller than the secret token.

3. Job Recruitment: - Develop a system that will help recruiting an ideal candidate person for a job. The system should have a set values such as job position, requirements etc. The system will the read application and determine whether certain candidate(s) qualify for the job.

4. Educational game: Develop a system that will allow a students to do a quiz on a subject of your choosing. The system should allow user to give answer, determine and output whether the answer was correct or otherwise.

Note: This topic can be implemented in various different ways (i.e. 2 student can both choose to do Educational game but one may choose to do English quiz, while the other may choose to do physics quiz.).Your teacher needs to approve your selected topic to ensure variety.
