Week 1: Your First Program: Data Types and Expressions – iLab
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.
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.
5. Be able to debug a simple program of any syntax and logic errors.
Your lab grade will be based upon:
1. the formatting of your source code;
2. the use of meaningful identifiers;
3. the extent of internal documentation; and
4. the degree to which an exercise’s specifications are met.
Preparation: If you are using the Citrix remote lab, follow the login instructions located in the iLab tab in
Course Home.
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

2. Choose File->New Project, and click Console Application. In the project name box,
enter LAB1A. 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 the Delete 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# program exactly as you see it. Use the tab where appropriate. (Note: C# is
case sensitive.) Instead of John Doe, type your name.
 class Hello
 {
 static void Main()
 {
 // display output
 System.Console.WriteLine(―John Doe‖);
 System.Console.WriteLine(―CIS170B – Programming using C#‖);
 System.Console.WriteLine(―nnnHello, world!nn‖);
 System.Console.WriteLine(―EOJ‖);
 System.Console.ReadLine();
 }
 }
Step 5: 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 6: Build Solution
To compile the program, click Debug on the menu bar and then click the Build Solution or Build
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

3. Once you have no compile errors, to execute or run your program, either:
 click Debug on the menu bar, and then Start Debugging;
 click the right arrow icon on the menu bar; or
 press the F5 key.
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 clicking File >> Close Solution. Now, create a new project
and name it LAB1B.
Step 2: Type in Program
Like before, delete the code that is automatically created and enter the following program. Type in your
name for Developer and current date for Date Written.
// —————————————————————
// Programming Assignment: LAB1B
// Developer: ______________________
// Date Written: ______________________
// Purpose: Ticket Calculation Program
// —————————————————————
 using System;
 class FirstOutputWithUsing
 {
 static void Main()
 {
 // create variables and load values
 int childTkts, adultTkts, totalTkts;
 childTkts = 3;
 adultTkts = 2;

 // process (calculation)
 totalTkts = childTkts + adultTkts;

 // display output

4.  Console.WriteLine(totalTkts);

 // pause
Console.Write(―nPress Enter to continue…‖);
Console.ReadLine();
 }
 }
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 Build on the menu bar and then click the Build Solution or Build
LabB option. 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, click Debug on 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 clicking File >> Close Solution.
2. Create a new project and name it LAB1C.
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!

5.  }
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 FlowchartInput: 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

6. 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

7. 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.
