o    // your code goes here!
o    }
Include a comment box like what you coded in Part B at the very top of your program.
Step 1a: Write Your Own Program

Write a program that calculates and displays the take-home pay for a commissioned sales employee after deductions are taken. The employee receives 7% of his or her total sales as his or her gross pay. His or her federal tax rate is 18%. He or she contributes 10% to his or her retirement program and 6% to Social Security. Use the Processing Logic provided in Step 2 below as a guide. The program’s output should look something like this:
Enter weekly sales:    28,000
Total sales:    $28,000.00
Gross pay (7%):    $1,960.00
Federal tax paid:    $352.80
Social security paid:    $117.60
Retirement contribution:    $196.00
Total deductions:    $666.40

Take home pay:    $1,293.60
Press any key to continue.

Step 2: Processing Logic
Basic Logic and Flowchart
Input: Prompt the user for the weekly sales.
Process: Perform the calculations. The employee receives 7% of his or her total sales as his or her gross pay. His or her federal tax rate is 18%. He or she contributes 10% to his or her retirement program and 6% to Social Security.
Output: Display the results.
Pseudocode:
1. Declare variables
2. Accept Input – weeklySales
3. Calculate Gross Pay = Weekly Sales * .07
4. Calculate Federal Tax = Gross Pay * .18
5. Calculate Social Security = Gross Pay * .06
6. Calculate Retirement = Gross Pay * .10
7. Calculate Total Deductions = Federal Tax + Social Security + Retirement
8. Calculate Total Take Home Pay = Gross Pay – Total Deductions
9. Display the following on separate lines and format variables with $ and decimal
1. Total Sales Amount: value of weekly sales
2. Gross Pay (.07): value of gross pay
3. Federal Tax paid (.18): value of federal tax
4. Social Security paid (.06): value of social security
5. Retirement contribution (.10): value of retirement
6. Total Deductions: value of total deductions
7. Take Home Pay: value of take home pay

Step 3: Save Program

Save your program by clicking File on the menu bar and then clicking Save Program.cs, or by clicking the Savebutton on the toolbar or Ctrl + S.
Step 4: Build Solution

To compile the program, click Debug on the menu bar and then click the Build Solution or Build LabCoption. You should receive no error messages. If you see some error messages, check the code above to make sure you didn’t key in something wrong. Double-click on an error to navigate to its location in the code. Once you make your corrections to the code, go ahead and click Debug >> Build Solution again.
Step 5: Execute the Program

Once you have no syntax errors, to execute or run your program, click Debug on the menu bar and then clickStart Debugging, or press the right arrow icon or the F5 key.
Step 6: Capture the Output

1. Capture a screen print of your output. (Do a PRINT SCREEN and paste into your MS Word document.)
2. Copy your commented code and paste it into the Word document.
End of Part C
END OF LAB

After you have completed your lab, complete the following for each part of the lab (if there are multiple parts).
1.    Capture a screen print of your output. (Do a PRINT SCREEN and paste into an MS Word document.)
2.    Copy your code and paste it into the same MS Word document that contains the screen print of your output.
3.    Save the Word document as CIS170B_Lab01_B_LastName_FirstInitial.docx.
4.    Upload all three projects folder and save the compressed file as CIS170B_Lab01_B_LastName_FirstInitial.Zip.
5.    Submit both the compressed project file and the Word document to the weekly Dropbox for this lab.
Zipping and Submitting Your Project Files
When you submit your project files, you will want to send the entire project folder that is created by MS Visual Studio when you create the project, along with your MS Word file. Use your favorite compression tool to zip the full contents of both projects, zip the single zip file, and submit the zip file to your Dropbox.

============= Week 2 =======================

Part A: Calculate Shipping Charge
Requirements

Your mission: Write a program that gets the amount of a purchase from the user and then calculates the shipping charge, based on the following table:
$0.00 – $250.00:    $5.00
$250.01 – $500.00:    $8.00
$500.01 – $1,000.00:    $10.00
$1,000.01 – $5,000.00:    $15.00
over $5,000.00:    $20.00
Sample output from program:
Enter a purchase amount to find out your shipping charges.
Please enter the amount of your purchase: 234.65
The shipping charge on a purchase of $234.65 is $5.00.
Press any key to continue . . .
Tips

Best practice: Put yourself in the place of the program. What questions would you ask a customer in order to get the best input? How would you determine the correct shipping charges if you had to make the decisions yourself? Write out the questions you would ask yourself on paper as pseudocode and/or in Visual Studio as C# comments, and then implement them one by one, testing as you go. Remember to not write too much at one time. Always add and test functionality incrementally!

You can use the pseudocode below as a guide:
Prompt the user for the sale amount
Is sale amount greater than $5,000.00?
If so, shipping is $20.00
If not, is sale amount greater than $1,000.00?
If so, shipping is $15.00
If not, is sale amount greater than $500.00?
If so, shipping is $10.00
If not, is sale amount greater than $250.00?
If so, shipping is $8.00
If not, is sale amount greater than $0.00
shipping is $5.00
If not
shipping is $0.00
If shipping is $0.00
Display “Error incorrect input”
If not
Display sale amount and shipping charge

Part B: TV Channel to Call Sign
Requirements

Your mission: Write a program that translates a TV channel (1 through 10) in your area to its respective call sign. For example, in the New York metropolitan area, channel 2 translates to WCBS. If a channel is unused in your area, tell the user that this is the case.
Sample output from program:
Translate TV Channel Number to Call Sign
Enter channel number: 1
Channel 1 is undesignated in your area
Enter channel number: 2
Call sign for channel 2 is WCBS
Enter channel number: 6
Call sign for channel 6 is WRNNDT

Tips

Best practice: Put yourself in the place of the program. What steps would you personally need to perform in order to process a channel translation yourself? Write out those steps on paper as pseudocode and/or in Visual Studio as C# comments, and then implement them one by one, testing as you go. Remember to not write too much at one time. Always add and test functionality incrementally!
Pseudocode: Although there are several valid ways to write the program, the following is an outline of one way to design the overall logic.
•    Declare variables for channel and call sign
•    Get channel number from user
•    Use appropriate decision structure to translate number to call sign
•    If number is valid in area
o    Print out translation
•    If not
o    Tell user this is the case

============= Week 3 =======================

 

Part A: Requirements - DIVE Scoring Program

Your mission: The state diving commission wants to computerize the scoring at its diving competitions. You've been hired to write a program to automate the scoring of dives. Following are the requirements for the program.

After each dive, the user will be prompted to enter the:

  • diver's name;
  • diver's city;
  • degree of difficulty (ranges from 1.00 to 1.67); and 
  • scores from five judges (scores can range from 0 to 10).

If an invalid score is entered, an error message will be displayed. The user will be prompted for the score repeatedly until a valid score is entered.

The program will then display the following information:

  • Diver's name
  • Diver's city
  • Dive final score: This is calculated by dropping the highest and lowest of the five judges' scores. The remaining three scores are added together, and the result is divided by 3 and then multiplied by the degree of difficulty.

The program will then prompt the user if she/he wants to process another dive. The user can type "Y" or "y" to continue, and "N" or "n" to quit.

Sample output:

Diver's name: Sue Jones 
Diver's city: Dallas
Dive degree of difficulty: 1.9
Invalid degree of difficulty - Please reenter (Valid Range: 1 - 1.67)
Dive degree of difficulty: 2
Invalid degree of difficulty - Please reenter (Valid Range: 1 - 1.67)
Dive degree of difficulty: 1.2

Judge #1 score: 45
Invalid score - Please reenter (Valid Range: 0 - 10)
Judge #1 score: 3
Judge #2 score: 4.5
Judge #3 score 6.7
Judge #4 score 89
Invalid score - Please reenter (Valid Range: 0 - 10)
Judge #4 score 8
Judge #5 score: 9.2

Diver: Sue Jones
City: Dallas
Dive score: 7.68

Do you want to process another dive (Y/N)? y

Diver's name: Dave Smith
Diver's city: Houston
Dive degree of difficulty: 1.1
Judge #1 score: 5.7
Judge #2 score: 6.8
Judge #3 score:: 7.6
Judge #4 score: 8.7
Judge #5 score: 6.7

Diver: Dave Smith
City: Houston
Dive score: 7.74

Do you want to process another diver (Y/N)? N

Tips

Best practice: Note that a good way to implement the code is to write a first version for only a single dive without validating input. Put yourself in the place of the program. What steps would you personally need to perform in order to process a single dive yourself? Write out those steps on paper as pseudocode and/or in Visual Studio as C# comments, and then implement them one by one, testing as you go. After you have a single dive process working, implement one of the input validations, or the outer loop that repeats the whole process. Whichever you choose, remember to not write too much at one time. Always add and test functionality incrementally!

Pseudocode: Although there are several valid ways to write the program, the following is an outline of one way to design the overall logic.

Declare and initialize variables: name, city,  judge score, highest score, lowest score, total score
Loop while there are dives to process

  • Get diver's name and city
  • Get degree of difficulty
    • Loop to validate input
    • End Loop
  • Loop five times to get judges' scores
  • Loop to Validate input
  • End Loop
  • Update highest and lowest scores if need be
  • Add score to total score
  • End Loop 
  • Calculate the final score (subtract highest and lowest scores from total score, divide by 3, multiply by degree of difficulty) 
  • Display the diver's information and final dive score
  • Prompt the user if he or she wants to process another dive
  • End-Loop
  •  

============= Week 4 =======================

 

iLab Steps

Step 1: Requirements – Phone Dialing Program
Your mission: A prepaid phone service needs a program that converts alphanumeric keyboard input into a phone number. The user will input eight characters and the program will output either an error message or the translated seven-digit phone number. The input may contain digits, letters, or both. Letters can be uppercase or lowercase.
The program will perform the conversion per a standard telephone keypad layout.
0     5    J K L
1     6    M N O
2    A B C    7    P Q R S
3    D E F    8    T U V
4    G H I    9    W X Y Z
The program implements the following methods.
•    Main(): Declares seven character variables and passes these to the following methods by reference:
o    ProcessInput(): gets user input and performs the conversion
o    ShowResults(): displays the results
•    GetInput(): Gets seven characters from the user and stores them into the seven variables Main() has passed by reference.
•    ProcessInput(): Calls ToDigit() for each, passing each character variable by reference, and returns one of these codes to Main() by value:
o    0 if there were no input errors
o    -1 if there were input errors
Input errors include the following:
•    The first character is 0 (seven-digit phone numbers can’t start with 0).
•    The first three characters are “555″ (no phone numbers start with 555).
•    Any character is not a digit or an uppercase or lowercase letter.
•    ToDigit(): Converts a character (passed by reference) to its corresponding digit per the table above, and returns one of these codes to ProcessInput() by value:
o     0 if the character is valid (a digit or uppercase or lowercase letter)
o    -1 if the character is not valid
•    ShowResults(): Writes converted telephone number to the screen, inserting a dash (-) between the third and fourth digits, and accepts the seven character variables from Main() by reference.
Sample Output:
Enter a 7 character phone number: 2132121
The converted phone number is: 213-2121
Enter a 7 character phone number: 2scdfER
The converted phone number is: 272-3337
Enter a 7 character phone number: 555resw
Invalid input, please try again.
Enter a 7 character phone number: 0988765
Invalid input, please try again.
Enter a 7 character phone number: 12345678
Invalid input, please try again.
Enter a 7 character phone number: @34*uy
Invalid input, please try again.
Tips
Best practice: Don’t try to write too much at a time! First, write an outline in comments based on the requirements and the pseudocode. Then, implement declaring seven char variables. Make sure to fix any compiler errors before implementing more. Then, write and call an empty GetInput() method that accepts parameters, but does nothing but return a dummy value. Make sure you can pass the seven character variables by reference without compiler errors before implementing any of the GetInput() logic. Keep working incrementally like this, testing as you go. Set breakpoints and use the debugger at each phase to make sure your logic is working correctly. Then, use the same approach to implement the other methods. Test each phase with valid input before handling any invalid conditions.
Pseudocode
•    ProcessInput( ) Method
o    Get 7 characters from the user and store them in the 7 variables that Main() has passed by reference
o    Call ToDigit() for each of the 7 characters
    If toDigit returns an error code (-1), return an error code (-1)
o    If the first character is 0, return an error code (-1) to Main()
o    If the first three characters are 555, return an error code (-1)
o    If there are no errors, return 0
•    ToDigit ( ) Method
o    Convert the characters (passed from ProcessInput() by reference) to upper case
o    Use a switch statement to translate characters into their corresponding digits.
    Write a case statement for each digit and for each valid uppercase letter
    Write a default case that returns an error code (-1) for invalid letters
o    If there are no invalid letters, return 0
•    ShowResults ( ) Method
o    Display the Phone Number using the character variables Main() has passed by reference
•    Main() Method
o    Declare 7 char variables
o    Get user input by calling the GetInput() method, passing it the 7 variables by reference
o    Perform the conversion by calling the ProcessInput( ) method, passing it the 7 variables by reference
o    Display an error message or call ShowResults(), depending on the code ProcessInput() returns

END OF LAB

============= Week 5 =======================

Part A: Tournament Stats
Requirements
Your mission: Write a program to determine statistics for a video game tournament. The user will input names and scores of all tournament players. The program will calculate the average score and display the players who scored below average.

The program will implement these functions:
•    Main(): Declares variables for the number of players and average score, and two arrays of size 100: one to store player names and the other to store their respective scores. Calls the following functions in sequence, passing necessary parameters by reference:
o    InputData( ): Gets player names and scores from the user and stores them into the two arrays for an unknown number of players up to 100.
o    DisplayPlayerData(): Displays each player’s name and score.
o    CalculateAverageScore( ): Calculates the average score and returns it by value.
o    DisplayBelowAverage( ): Displays the names and scores of players who scored below average.
Sample output:

Enter Player Name (Q to quit): Bob

Enter score for Bob: 3245

Enter Player Name (Q to quit): Sue

Enter score for Sue: 1098

Enter Player Name (Q to quit): Dave

Enter score for Dave: 8219

Enter Player Name (Q to quit): Pat

Enter score for Pat: 3217

Enter Player Name (Q to quit): Q
Name Score

Bob 3245

Sue 1098

Dave 8219

Pat 3217
Average Score: 3944.75
Players who scored below average

Name Score

Bob 3245

Sue 1098

Pat 3217

Press any key to continue . . .
Tips
Best practices: Don’t try to write too much at a time! First, write an outline in comments based on the requirements and the pseudocode. Then, implement each function one at a time. Start each by writing a shell that just accepts data and perhaps prints it out for testing purposes. Test by calling the function from Main(). Then, add more functionality. Keep working incrementally, compiling and testing as you go. Set breakpoints and use the debugger at each phase to make sure your logic is working correctly. Then, use the same approach to implement each of the other functions.
Pseudocode
•    Main Function
o    Declare player and score arrays, and variables for number of players and average score.
o    Call the InputData( ) function, passing arrays and number of players variable by reference
o    Call the DisplayPlayerData( ) function, passing arrays and number of players variable by reference
o    Call the CalculateAverageScore( ) function, passing arrays and number of players by reference. Store returned value in average variable.
o    Display the average score
o    Call the DisplayBelowAverage( ) function, passing arrays and number of players variable by reference, passing average variable by value

•    InputData function
o    Loop while the number of players is less than the length of the array
o    Prompt for the player’s name
o    If the user entered Q, break out of the loop
o    Prompt the user for the player’s score
o    Add 1 to the number of players

•    DisplayPlayerData function
o    Loop to display the name and score of each player

•    CalculateAverageScore function
o    Loop to add up the scores
o    Divide by the number of players to calculate the average score
o    Return the average score to main

•    DisplayBelowAverage function
o    Loop to display the names and scores of all players who scored below the average score

END OF PART A

Part B: Alphabetical Order
Requirements
Your mission: Write a program to alphabetize a list of last names. The user will input an undetermined number of last names. The program will display the number of names entered and alphabetized lists of the names in ascending (A-Z) and descending (Z-A) order.

Your program will store the names in an ArrayList object. It will use various ArrayList properties and methods to implement the program requirements.
Sample output:

Enter a last name: Roberts
Keep going? (Y/N): y
Enter a last name: DeLay
Keep going? (Y/N): y
Enter a last name: Foreman
Keep going? (Y/N): y
Enter a last name: Ganguly
Keep going? (Y/N): n
4 last names entered

Names in Ascending Order

DeLay
Foreman
Ganguly
Names in Descending Order

Roberts
Ganguly
Foreman
DeLay
Tips
Best practices: Don’t try to write too much at a time! First, write an outline in comments based on the requirements and the pseudocode. Then, work on instantiating an ArrayList object, followed by implementing the loop that will get user input. As always, keep things simple and implement incrementally. Review the list of ArrayList methods and properties in the textbook and experiment with the ones you think you’ll need.
Pseudocode
•    Main function
•    Instantiate ArrayList object
•    Loop to get last names, until user wants to quit
o    Add each last name to the ArrayList
•    Display the count of the last names
•    Sort the ArrayList
•    Loop to display the names
•    Reverse the order of the ArrayList
•    Loop to display the names
