Assessment Instructions
What do you need to do for this assessment?
Task:
Develop an ATM simulator using C programming language. Your work should be presented in a report format and must cover all the requirements below.
Automated teller machine (ATM) has two input devices: Card reader and Keypad. The ‘Card Reader’ reads the information contained in the card's magnetic strip/microchip. Then ATM software asks the user to insert the correct PIN of the card using the ATM keypad, i.e., PIN is usually a four-digit number. If the two PIN numbers are identical, login is given to ATM services and to the account information. The card's PIN and user account information, e.g., balance, are typically stored in a remote database(s)/file(s).
But for sake of simplicity, assume the ATM is only dealing with two pre-initialized cards, Card 1 and Card 2. Card 1 PIN is initialized by 1234, and an initial balance of, £1234.60. Card 2 PIN is initialized by 5678, and an initial balance of, £848.50.
Your program will prompt the user to select Card 1 or Card 2. Then it will request the user to insert the card's PIN using the keyboard. Only three attempts are given to the user to insert the correct PIN. If the user attempts are exceeded, then the card will be blocked automatically. The ATM program should output a message that the card has been retained and prompt the user to contact the bank.
If the PIN code is entered correctly, the user should be able to:
• Change the selected card PIN.
• Check the balance.
• Withdraw money as a multiple of £5, £10 and/or £20 if the available balance is enough. (Note: This updates the selected card balance.)
• Deposit money (any amount) into the account. (Note: This updates the selected card balance.)
• Eject the selected card and select another one without quitting the program.
• Quit the program and return the card.
In each operation, the user should have the option to see or not to see a receipt on the screen showing the original balance and the transaction type and the new balance after the transaction.
The user must be able to do as many transactions as desired after completing each transaction by having the option to quit or return to the main menu.
All transactions performed in a single program should be saved in a text file in their order of occurrence, i.e., the transactions' receipts information with their order of occurrence.
Ensure clear prompts to users, assuming they have no understanding of how the program functions. Your programs should not exit unexpectedly.
Guidance:
For this assessment, you should make use of the following themes/activities that you have already completed. These activities have been designed to support this summative assessment:
• Number Systems in computing and Basic Data Types, Introductory C Language Topics, Program Design Implementation and Testing, and Complex data structures.
• Reference book Section 1: Introductory C Language Topics, Section 2: Design Implementation and Testing and Section 3: Complex data structures.
Testing.
Unit and integration testing will be key to proving that the software produced is reliable.
Please note:
This is an individual assessment, so you should not work with any other student.
Structure:
This assessment will require at least 2 parts:-
1) The report as detailed below as a word document or pdf.
Your report must include:- Title page, contents page, page numbers and declaration of ownership
Section 1: Algorithm – The designed/Used algorithm expressed as a Jackson Structured Diagram
Section 2: Technical Overview – A description of the all the variables, functions and data structures used needs to be included.
Section 3: Testing Plan – A detailed testing plan table(s), mentioning if it follows Blackbox testing, Whitebox testing, record testing, etc.
Section 4: Testing and Evaluation – Your Testing Plan table(s) including the obtained outputs through your code. Confirm if they match the expected outputs. Comment on any differences between the expected and the obtained outputs.
Section 5: Summary – a short (no more than one page) and accurate reflection of how well you think the solution works and what improvements are needed or could be made as a future work.
Section 6: References – All used resources including the module reference book.
2) A C file containing the complete source code. + any text files
C Code with Comments. The complete working C program implementation of your algorithm, which has comments in the code describing what it does.
Theory and/or task resources required for the assessment:
You need a good understanding of numerical Fundamentals of Numeric Data, Data Types, Algorithms and Abstraction and Decomposition themes for this assessment.
Referencing style.:
Literary references should be in the Harvard style, and any resources used must be referenced in a bibliography.
Expected word count:
You should write no more than 1 page for each section. Note that this is a limit, not a target. There is no minimum word count, and you should be succinct in your writing and avoid repetition. Use diagrams, lists and tables wherever possible.
The Reference and Appendix sections are not included in the word count. You may write additional appendices as needed.
Learning Outcomes Assessed:
- Programme in C and illustrate good coding practice through the design and verification of simple control programmes
- Apply a range of programming techniques and functions in programming (e.g., arithmetic operators, standard output, precedence, local variables and Boolean expressions, global variable, parameters, return values, frames, strings and command line arguments)
- Compile and debug software
