Grade Descriptor

Indicative characteristic/s

Contextualisation

• Complex problems with more than one variable have been explored

• Standard methods used to design the proposed solution.  This has been clearly documented to a high standard.
• Within the planning of the programmed solution a number of components and options have been presented and a possible solution has been devised.
• All research has been clearly identified and documented.

• The selection of methods and techniques/sources has been justified

• The design of methods/techniques has been justified.

• This can be evidenced through the use of formal documentation for the tasks.
• All research has been clearly identified and documented.
• The program has been fully broken down into appropriate procedures showing good use of parameters.

• The validity of the results has been evaluated using defined criteria.
• Realistic improvements have been proposed against defined characteristics  for success

• Actual test results have been analysed against expected results to identify discrepancies.

The program has been evaluated and appropriate recommendations for improvements have been made.

D3 – Demonstrate convergent/lateral/creative thinking

• Convergent and lateral thinking have been applied

• Problems have been solved

• Innovation and creative thought have been applied

• At this level ideas generated and decisions taken are original, creative and appropriate.  This can be evidenced in most tasks.
• Clear evidence of developing programming skills to solve problems encountered, especially the use of validation of user input to ensure a robust program, and more advanced features have been demonstrated.
• Innovative and creative thinking has been shown in solving these problems.  Student has clearly demonstrated alternative ways of solving problems and not just used standard solutions.

To enable learners design, implement and evaluate a procedural program for an organisation.

Your employer has asked you to write a program to manage the company’s daily Sales and Purchases.  The program needs to give the user the option of entering details of a Sale or details of a Purchase.

The user will need to log into the system to access the transaction menu.  When the Sales option is selected from the transaction menu the user will be required to enter the sales price and sales costs (it should not be possible to enter negative figures for either the sales price or sales costs).  The program must then calculate and display the net sales price (sales price – sales costs).  Following that the user will be given the option of entering another sale or returning to the main menu.  The program will keep a running total of the net sales prices.

When the Purchases option is selected the user will be required to enter the purchase price and the transaction costs (Again, there should be some validation to ensure that negative numbers are not entered).  The program must then calculate and display the overall purchase price (purchase price + transaction costs). Following that the user will be given the option of entering another purchase or returning to the main menu.  The program will keep a running total of the overall purchase costs.

When the user selects to quit the program a final report must be displayed showing the total sales and the total purchases and the overall balance of the cash flow for the day.  You should include any further information in the report that you think useful, for example, the average sales price, the average purchase price, a complete listing of all transactions, the highest sales price or the highest purchase price.

An added feature that you also need to implement is an onscreen help system, to explain to the user how to use the program

Your program should contain at least one sub procedure which uses parameters.

1.    Identify the program inputs, outputs and functions needed.

2.    Design the program using a Structure Chart or Structured English (or any other standard design method) paying particular attention to loops and selection statements.

3.    Create a Test Plan and Test Data to test your program using both valid and invalid data.

1.    Code your program in C++ following your prepared design.

1.    Test your program following your prepared test plan and show the results using screen shots.

2.    Analyse actual test results against expected results to identify discrepancies.

3.    Evaluate your program and make recommendations for improvements following feedback from your tutor.

1.    Create onscreen help to assist the users of the program.

1.    Create Program Documentation for the support and maintenance of the program. This should include:

·        The programming structures used;

·        A list of the variables used in the program, explaining what they are used for and their scope and data type;

·        A complete annotated listing of your program.

1. The complete design for the program as detailed above.
2. The test plan, test data and test results, together with an explanation of errors encountered and how you resolved them, and an evaluation of the program.
3. The onscreen help file.
4. The complete Program Documentation as detailed above.

Create Program Documentation for the support and maintenance of the program. This should include:

·        The programming structures used;

·        A list of the variables used in the program, explaining what they are used for and their scope and data type;

·        A complete annotated listing of your program.
