1 Marking rubric for Assignment #2 The TAs marked the following sections: Yu: Section A Questions -4, Section B Questions -3 Megan: Section B Questions 4-5 Assignment #2 Marking Rubric: A. WriteUp Please mark all 4 questions as follows:. Marks - One mark for each expression (.5 mark for correct operator precedence labeled,.5 mark for correct evaluation value) Marks - One mark each for getting ranges (a)-(c) correct, and two marks for (d) 3. 5 Marks 5 marks for a correct for loop which prints the odd numbers, - if they did not increment the for loop counter by 2 within the for statement 4. 5 Marks 5 marks for a correct do loop that prints the same set of numbers as the provided while loop B. Programming Questions All Prompts and Output text should match exactly as shown in the example test run. If they do not exactly match, deduct 2 marks. Comments are worth 2% of each question (% for clear class and method comments, % for being Javadoc compliant) Failure to submit a file, or submitting a file that does not compile in CSIL results in zero for that question.. RandomAvg Marks 2 Marks Input Validation loop re-prompts if non-int value specified 2 Marks Average correctly computed as float Mark Average formatted to 3 decimals places Mark Largest number correctly calculated Mark - Smallest number correctly calculated 3.4 Bob

2 The following inputs should be accepted and produces valid output: 2. AvgNums Marks 2 Marks Input Validation loop re-prompts if non-int values specified Mark Correctly accepts to input integers Mark Correctly rejects more than input numbers or inputs with strings or floats 2 Marks Average correctly computed as float Mark Average formatted to 3 decimals places 3.4 Bob 5 bob seven The following inputs should be accepted and produces valid output: Distance Marks 2 Marks Input Validation loop re-prompts if non-int values specified Mark Correctly accepts exactly 4 input integers including negative numbers Mark Correctly rejects anything other than 4 input ints 2 Marks Distance correctly computed as float Mark Distance formatted to 3 decimals places Bob

3 The following inputs should be accepted and produces valid output: MoneyChanger 5 Marks Mark Input Validation loop re-prompts if non-float value specified Mark - Entering a String causes the user to be re-prompted Mark Correctly accepts both integer and decimal numbers with one or two decimals Mark Correctly rejects floats with more than 2 decimal places Mark Correctly rejects negative numbers 5 Marks Correctly calculates the number of each bill or coin 2 Marks Correctly outputs the singular or plural of each bill or coin as appropriate Mark - Class and Methods well commented 2 Marks - Class and Method comments Javadoc compliant - Mark For each missing monetary denomination (besides missing denominations) $57.63 Money The following inputs should be accepted and produces valid output: MoneyCounter 3 Marks 5 Marks Passes Testcase 5 Marks Passes Testcase 2 4 Marks Passes Testcase 3 and 4 Mark - Defines enum CurrencyAmt 5 Marks Well structured code with at least private method 2 Marks Correctly parses all bill and coin names both plural and single 2 Marks Correct ignores any lines which are not in the correct format 4 Marks - Class and Methods well commented 2 Marks - Class and Method comments Javadoc compliant - Mark For each missing monetary denomination (besides missing denominations) +5 Bonus Marks Passes Testcase 5

4 The following test cases should be accepted and produce valid output: Testcase : Sample output from MoneyChanger as input, Correct Answer: $57.63 Enter monetary amount: $57.63 "$57.63" is not a double. Please enter a monetary amount as a double: That's equivalent to: 2 twenty dollar bills ten dollar bill five dollar bill toony loonies 2 quarters dime nickels 3 pennies Testcase 2: Example Test Run from Assignment, Correct Answer: $7.28 ten dollar bill But wait, I have more ten dollar bills coming! 5 ten dollar bills quarter ten dollar bills 3 pennies Testcase 3: Example Test Run from Assignment, Correct Answer: $2.34 From Linux, pipe the output of MoneyChanger directly into MoneyCounter and enter an amount (in the example below, I entered 2.34 into MoneyChanger, which generated output which was piped into MoneyCounter as input. MoneyCounter should report the same amount. java MoneyChanger java MoneyCounter $ java MoneyChanger java MoneyCounter 2.34 Your total amount of cash is: $2.34 Testcase 4: Repeat Testcase 3 but Enter the value when prompted $ java MoneyChanger java MoneyCounter Your total amount of cash is: $. Testcase 5: Successfully handles EOF to terminate

5 Scott This testcase uses the output from MoneyCounter (with input 38.4) which is redirected to a file called mc38.4 which has the last line with the number of pennies deleted. This tests if the student s program successfully checks for end-of-file as well as for Penny at the end. $ java MoneyCounter <mc38.4 Your total amount of cash is: $38.4
