iLAB OVERVIEW

Scenario and Summary

Welcome to Programming with C#. The purpose of this three-part lab is to walk you through the following tutorial to become familiar with the actions of compiling and executing a C# program.

Deliverables

Submit the following to this week's Dropbox:

  1. A zipped Visual Studio project folder for each programming exercise. Refer to the Deliverables section of the Week 1 iLab page for detailed instructions on how to zip a project folder.
  2. A single MS Word file named YourLastName_Lab1_ex1.docx, containing the following items:
  3. The source code for each part/exercise: Your source code should use proper indentation, include meaningful comments, and be error free. Start each with a specification that includes your name, the lab and exercise number, and a description of what the program accomplishes, similar to this:

/* Specification:
First Name Last Name
Lab 1 Exercise #
This program does X */

  • Labeled screenshot(s) demonstrating that each exercise produces correct results

NOTE: A screenshot of a window can be created by first clicking on it to activate it. Next, press the key or key combination your specific computer uses to do a "print screen" (typically the PrntScrn or Prnt key in combination with the ctrl or FN key). Then, click the MS Word "paste" option to paste the screenshot into the MS Word file.

Objectives and Grading

Lab Objectives:

  1. How to create a project
  2. How to enter and save a program
  3. How to compile and run a program
  4. Given a simple problem using input and output, be able to code and test a program that meets the specifications.

iLab Steps

Part A: Getting Started

Step 1:Start the Application
Locate the Visual Studio 2010 icon and double click to open. Under Applications, click on the Microsoft Visual Studio.NET 2010 icon to open the C# software.
Step 2:Create a C# Console Project
ChooseFile->New Project, and clickConsole Application. In the project name box, enterLAB1A. Your screen should look like the screen below. If so, press the OK button.

Step 3:Delete All Code in Program.cs
Your screen should now look like what you see below. Now, highlight all of the code that you see [Ctrl+ A] and press theDelete key. You will not need this code because you will now be getting experience writing every line of a new program.

Step 4:Type in Program
Now enter the following C# programexactlyas you see it. Use the tab where appropriate. (Note: C# is case sensitive.) Instead of John Doe, type your name.
  • classHello
  • {
  • static voidMain()
  • {
  • // display output
  • System.Console.WriteLine("John Doe");
  • System.Console.WriteLine("CIS170B – Programming using C#");
  • System.Console.WriteLine("\n\n\nHello, world!\n\n");
  • System.Console.WriteLine("EOJ");
  • System.Console.ReadLine();
  • }
  • }

Step 5:Save Program
Save your program by clickingFileon the menu bar and then clickingSave Program.cs, or by clicking theSavebutton on the toolbar orCtrl + S.
Step 6:Build Solution
To compile the program, clickDebugon the menu bar and then click theBuildSolutionorBuild LabAoption. You should receive no error messages in the Error List window below the program. If you see some error messages, check the code above to make sure you didn't key in something wrong. You can double click on each error message to better navigate to the area where the problem might be. Once you make your corrections to the code, go ahead and build the solution again.
Step 7:Execute the Program
Once you have no compile errors, to execute or run your program, either:
  • clickDebugon the menu bar, and thenStart Debugging
  • click theright arrow iconon the menu bar; or
  • press theF5key.

Step 8:Capture the Output
Print a picture of your screen output. (Do a print screen and paste this into your MS Word document.)
Step 9:Print the Source Code
Copy your source code and paste it into your Word document.
End of Part A

Part B: Calculate Total Tickets

Step 1:Create New Project
Make sure you close your previous program by clickingFileClose Solution. Now, create a new project and name itLAB1B.
Step 2:Type in Program

// Developer: / ______
// Date Written: / ______
// Purpose: / Ticket Calculation Program
// ------
  • usingSystem;
  • class FirstOutputWithUsing
  • {
  • static voidMain()
  • {
  • // create variables and load values
  • intchildTkts, adultTkts, totalTkts;
  • childTkts = 3;
  • adultTkts = 2;
  • // process (calculation)
  • totalTkts = childTkts + adultTkts;
  • // display output
  • Console.WriteLine(totalTkts);
  • // pause
    Console.Write("\nPress Enter to continue...");
    Console.ReadLine();
  • }
  • }

Step 3:Save Program
Save your program by clickingFileon the menu bar and then clickingSave Program.cs, or by clicking theSavebutton on the toolbar orCtrl + S.
Step 4:Build Solution
To compile the program, clickBuildon the menu bar and then click theBuildSolutionorBuild LabBoption. 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. Once you make your corrections to the code, go ahead and click Build > Build Solution again.
Step 5:Execute the Program
Once you have no syntax errors, to execute or run your program, clickDebugon the menu bar and then clickStart Debugging.
Step 6:Comment the Program
Go back to the editor and insert meaningful comments that show that you understand what each line of code does.
Step 7:Capture the Output
  1. Run the program again.
  2. Capture a screen print of your output. (Do a PRINT SCREEN and paste into your MS Word document.)
  3. Copy your commented code and paste it into your document

End of Part B

Part C: Payroll Program

Step 1:Create a New Project
  1. Make sure you close your previous program by clickingFileClose Solution.
  2. Create a new project and name itLAB1C.
  3. This time, do not delete the code that gets automatically created. Instead, insert your code right between the curly braces, as illustrated below.
  • static void Main(string [] Args)
  • {
// your code goes here!
  • }
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 clickingFileon the menu bar and then clickingSave Program.cs, or by clicking theSavebutton on the toolbar orCtrl + S.
Step 4:Build Solution
To compile the program, clickDebugon the menu bar and then click theBuildSolutionorBuild 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, clickDebugon the menu bar and then clickStart Debugging, or press theright arrow icon or theF5key
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.
