CIS170C-Week 2 Lab Instructions

Lab 2 of 7: Decisions and Repetition

Lab Overview—Scenario/Summary

You will code, build, and execute two programs requiring decisions. The first program will determine the smaller of two numbers input on the screen. The second program will calculate the number of calories burned on a treadmill using repetition.

Learning outcomes:

1. To be able to design program logic using either a flowchart or pseudocode
2. To be able to define and use data types
3. To be able to prompt the user for input
4. To be able to use the assignment statement for calculations
5. To be able to display output to the console in a formatted manner
6. To be able to debug a program of syntax and logic errors
7. To be able to make decisions
8. To be able to use repetition.

Lab Steps

Preparation:

If you are using the Citrix remote lab, follow the login instructions located in the lab (under General Resources within Course Resources) in Course Home.

Locate the Visual Studio 2015 icon, and launch the application.

Part A: Determine Smallest Number
Step 1: Requirements
Write a program that inputs two numbers and determines which of the two numbers is the smallest. If the numbers are equal, display a message that they are equal.

Sample output from program:

You will be asked to enter two numbers.
The smallest value will be displayed or a message if they are the same.

Please enter a numeric value: 4
Please enter a numeric value: 7

The smallest value is 4
Press any key to continue.

AND THEN:

Please enter a numeric value: 7
Please enter a numeric value: 4

The smallest value is 4
Press any key to continue.

Step 2: Pseudocode
Using the pseudocode below, write the code that will meet the requirements.

Display description of the program.
Prompt the user for the first number.
Prompt the user for the second number.
If first number equals second number
Display the two numbers are equal
Else
If first number is greater than second number
Assign second number to smallest
Else
Assign first number to smallest
End-If
Display smallest number
End-If

Step 3: Create a New Project
Create a new project and name it LAB2A. Write your code using the processing logic in Part A, Step 2.
Step 4: Save Program
Save your program by clicking File on the menu bar and then clicking Save Program.cpp, or by clicking the Save button on the toolbar, or Ctrl + S.

Step 5: Build Solution
To compile the program, click Debug and then Build solution (F7). 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 6: Execute the Program
Once you have no syntax errors, to execute or run your program, click Debug on the menu bar, and then click Start Debugging.

Step 7: Capture the Output

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 Lab02A_LastName_FirstInitial.

Part B: Calories Burned
Step 1: Requirements
Write a program that uses a loop to display the number of calories burned after running on a treadmill for 10, 15, 20, 25, and 30 minutes. Running on a treadmill burns 3.9 calories per minute.

Sample Output from Program:
39.0 calories were burned after 10 minutes.
58.5 calories were burned after 15 minutes.
78.0 calories were burned after 20 minutes.
97.5 calories were burned after 25 minutes.
117.0 calories were burned after 30 minutes.
Press any key to continue.
Step 2: Pseudocode
Using the pseudocode below, write the code that will meet the requirements.

Display program information
Declare variables
For i=10 to 30 step 5
Print i*calories
End for
Step 3: Create a New Project
Create a new project and name it LAB2B. Make sure you close your previous program by clicking File >> Close Solution. Write your code using the Processing Logic in Part B Step 2.
Step 4: Save Program
Save your program by clicking File on the menu bar and then clicking Save Program.cpp, or by clicking the Save button on the toolbar, or Ctrl + S.

Step 5: Build Solution
To compile the program, click Debug then Build solution (F7). 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 6: Execute the Program
Once you have no syntax errors, to execute or run your program, click Debug on the menu bar, and then click Start Debugging.

Step 7: Capture the Output

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 Lab02B_LastName_FirstInitial.
