Overview

This laboratory will have you using while loops and if statements, among other control structures. You will also create a new class, instantiate an instance of that class, and call a function within that class. First you will create a console application that has you enter passing or failing grades - it will calculate the number of each and provide responses based on the total number of each pass or failure. Second you will use visual programming to create a "Memory" game where you select two cards at a time, if they match, you remove those cards. You continue this process until all of the cards are matched.

Procedures

1. Grade analysis console application
   • View a finished release candidate
   • Open a new instance of VS08
   • New Project... > Console Application > Name it: Analysis (pay attention to where you save it)
   • Right click on the project name in Solution Explorer (in bold), select Add > New Item...
     • Choose Class
     • Name it: doAnalysis.cs
     • Click Add
   • Inside class doAnalysis
     • Create a function: public void ProcessExamResults()
   • Inside Main
     • Instantiate a new instance of doAnalysis
     • Use that instance to call ProcessExamResults()
   • Inside ProcessExamResults()
     • Declare and initialize 4 integers: passes, failures, studentCounter, results
     • Use a while loop to prompt the user 10 times (use studentCounter)
       • Prompt the user to: Enter result (1 = pass, 2 = fail):
       • Store the user input into the variable result
       • Use an if...else to determine whether the result is a 1 or a 2
         • if the result is a 1, increment the variable passes by 1
         • else if the result is a 2, increment the variable failures by 1
       • increment the studentCounter
         • Note: if you forget to increment the counter, you'll get an infinite loop and your program will "hang" and eventually use up so much memory that it crashes.
     • After the while loop, write out the number of passes and failures using the format item {0}
     • Then use the ternary operator to test if passes is greater than failures, if so write "Great Job", if not write "Get some tutors"
     • The use an if statement to see if passes is greater than 8. If so, write "Raise tuition"
     • Finally, write out a message to press the Enter key to continue and wait so the user can see the result
   • Test your project
      
2. Memory Matching game
   • View a finished release candidate
   • Open a new instance of VS08
   • New Project... > Windows Forms Application > Name it: Memory (pay attention to where you save it)
   • Layout
   • Use these images | cardPair_sm.png:
     • background, cardback, icon, kitten, puppy, monkey, bear, road runner, wile e coyote
   • Layout the controls in the application similar to what you see in the release candidate
     • form should be 900 x 650 pixels
     • add background image
     • add icon
     • add 12 pictureBox instances to the form (100 x 100 pixels)
     • add a title label (approx 40pt, centered at top)
     • add a congratulations label (approx 40pt, centered in middle)
     • add a play again button (centered in middle below congrats)
     • add a label containing your name in the lower right corner (10pt)
   • Coding
   • Declare private variables:
     • need 12 int's: card1 through card12
     • need int's: randomNum, numMatches, counter, numSelectedCards, firstSelectedCard, totalNumMatchesRemoved
   • Inside Form1() constructor
     • Set the congrats label and play again button visibility to false
     • Initialize the pictureBox image location to cardBack.jpg for all 12 pb's
     • Randomly create 6 matches - use a switch
   • Add 12 Event Handlers, one for each pictureBox on the form
     • increment numSelectedCards
     • Check to see which picture to display (see if cardx is equal to 1-6)
       • Set the image location based on whether the value is 1,2,3,4,5,6
     • if there are two cards selected
       • Pause the application
       • if the firstSelectedCard is cardx
         • find the two cards and remove them from the screen
         • use an if...else if
         • Increment the total number of matches removed
         • Check to see if the total number of matches removed is 6
           • if so, display the congrats label and play again button
       • else - when the firstSelectedCard is not cardx
         • Set the image location of all 12 pb's to cardBack.jpg
       • Set the number of selected cards and the first selected card back to zero 0
     • else if the first selected card is 0
       • Set the value of the first selected card to be equal to cardx
   • Add an Event Handler for the play again button
     • Re-initialize all variables
     • Set the congrats label and play again button visibility to false
     • Set the visibility of all 12 pb's to true
     • Initialize the pictureBox image location to cardBack.jpg for all 12 pb's
     • Randomly create 6 matches - use a switch
   • Test your project
      
3. Finalization (do this for both applications)
   • Build > Configuration Manager
     • Change "Active solution configuration" to Release.
     • Make sure "Configuration" changes to Release.
     • Close
   • Rebuild
   • Look in <project folder> / bin / Release
     • Double click <projectName>.exe
        
4. On your own
   • Write the pseudocode for each application in a large comment block at top of the .cs files. Be thorough with your pseudocode. It should be easily readable by anybody (regular english terminology). Essentially, if there's a line of code, there should be a line of pseudocode. You do not have to write pseudocode for the "layout" code.
      
5. Turn in both entire projects.
